I have still experienced this buggy using gnome-terminal and its menubar after upgrading to Ubuntu Precise. I have fixed it now by installing any missing recommends, using "sudo apt-get install --fix-policy --install-recommends". One or multiple of the packages this installed appears to have fixed it. And it is likely to be a package which is present when installing Oneiric from scratch (where this is a non-issue for me). Here's the list of packages containing "menu" or "indicator" in its name: appmenu-gtk3 0.3.0-0ubuntu1 gir1.2-dbusmenu-gtk-0.4 0.5.1-0ubuntu2 gnome-menus 3.2.0-0ubuntu2 indicator-status-provider-mc5 0.5.0-1 And here's the full list of packages this pulled in: % awk '/2011-12-17 14:1.*status installed/ {print $5 " " $6}' /var/log/dpkg.log | sort -u apg 2.2.3.dfsg.1-2 appmenu-gtk3 0.3.0-0ubuntu1 automake1.4 1:1.4-p6-13.1 bamfdaemon 0.2.104-0ubuntu1 c2esp 21-1 colord 0.1.15-1 cowbuilder 0.65ubuntu1 cowdancer 0.65ubuntu1 cpu-checker 0.7-0ubuntu1 cups 1.5.0-13bzr1 deja-dup 21.2-0ubuntu2 desktop-file-utils 0.18-1ubuntu3 dma-migrate 0.0.2010.06.17-11 doc-base 0.10.3 docutils-doc 0.8.1-4 duplicity 0.6.17-0ubuntu1 ebtables 2.0.9.2-2ubuntu2 enchant 1.6.0-6 erlang-syntax-tools 1:14.b.4-dfsg-1ubuntu1 firefox-locale-de 9.0~b6+build1-0ubuntu1 florence 0.5.0-2 fontconfig 2.8.0-3ubuntu2 fonts-horai-umefont 434-1 fonts-kacst 2.01+mry-3 fonts-nanum 3.010-2 gconf2 3.2.3-1ubuntu1 gir1.2-dbusmenu-gtk-0.4 0.5.1-0ubuntu2 gir1.2-gst-plugins-base-0.10 0.10.35.2-2build1 gir1.2-gstreamer-0.10 0.10.35.2-1ubuntu1 gir1.2-panelapplet-3.0 1:2.32.1-0ubuntu6.5 gir1.2-panelapplet-4.0 1:3.2.0-0ubuntu1 gir1.2-rb-3.0 2.90.1~20111126.89c872b0-0ubuntu2 gir1.2-wnck-3.0 3.2.1-1 gnome-applets 3.2.0-0ubuntu1 gnome-menus 3.2.0-0ubuntu2 gnome-online-accounts 3.2.1-2 gnome-orca 3.3.2-0ubuntu2 gnome-panel 1:3.2.0-0ubuntu1 gnome-session-fallback 3.2.1-0ubuntu4 gnome-themes-standard 3.2.1-0ubuntu2 hicolor-icon-theme 0.12-1ubuntu1 ibus-gtk3 1.4.0-1ubuntu3 icoutils 0.29.1-2 indicator-status-provider-mc5 0.5.0-1 install-info 4.13a.dfsg.1-8ubuntu1 iw 3.1-1 kompare 4:4.7.3-0ubuntu1 kubuntu-debug-installer 11.10ubuntu1 kvm-ipxe 1.0.0+git-2.149b50-1ubuntu3 libalgorithm-c3-perl 0.08-1 libcanberra-gtk3-module 0.28-0ubuntu12 libcanberra-gtk-module 0.28-0ubuntu12 libc-bin 2.13-23ubuntu1 libclass-c3-perl 0.23-1 libclass-c3-xs-perl 0.13-1build2 libclass-method-modifiers-perl 1.08-1 libclutter-1.0-common 1.8.2-2ubuntu1 libcogl-common 1.8.2-1 libcommons-codec-java 1.5-1 libdmapsharing-3.0-2 2.9.14-1 libdom4j-java 1.6.1+dfsg.2-5 libfile-rsyncp-perl 0.68-1.1build6 libfolks-eds25 0.6.5-2 libftdi1 0.19-3 libgail-gnome-module 1.20.3-1 libgd-gd2-noxpm-perl 1:2.46-2build1 libglib2.0-0 2.31.4.tested-0ubuntu3 libgphoto2-l10n 2.4.11-3.1 libgtk-3-0 3.3.4-0ubuntu2 libhtml-form-perl 6.00-1 libio-dirent-perl 0.04-2build2 libjaxme-java 0.5.2+dfsg-5 libjpeg-progs 8c-2ubuntu4 liblog4j1.2-java 1.2.16-2ubuntu2 libltdl-dev 2.4.2-1ubuntu1 libmagickcore4-extra 8:6.6.9.7-5ubuntu2 libmail-sendmail-perl 0.79.16-1 libmono-i18n4.0-cil 2.10.5-1ubuntu1 libmono-i18n-west4.0-cil 2.10.5-1ubuntu1 libmro-compat-perl 0.11-1 libmtp-runtime 1.1.1-1 libnetpbm10 2:10.0-15 libnet-snmp-perl 6.0.1-2 libpackage-stash-xs-perl 0.24-1build1 libpam-winbind 2:3.5.11~dfsg-4ubuntu3 libpanel-applet2-0 1:2.32.1-0ubuntu6.5 libpanel-applet-3-0 1:2.32.1-0ubuntu6.5 libpanel-applet-4-0 1:3.2.0-0ubuntu1 libqapt1 1.2.65-0ubuntu1 libqapt-runtime 1.2.65-0ubuntu1 libqt4-sql-sqlite 4:4.7.4-1ubuntu6 librhythmbox-core4 2.90.1~20111126.89c872b0-0ubuntu2 librsync1 0.9.7-8 libsctp1 1.0.11+dfsg-2 libssl-doc 1.0.0e-2ubuntu4 libsys-hostname-long-perl 1.4-2 libvirtodbc0 6.1.3+dfsg1-1ubuntu3 libx11-doc 2:1.4.4-4 libxom-java 1.2.1-3 libxpp2-java 2.1.10-7 libxpp3-java 1.1.4c-2 linux-headers-3.2.0-5-generic 3.2.0-5.11 linux-headers-generic 3.2.0.5.5 lirc 0.9.0-0ubuntu1 lksctp-tools 1.0.11+dfsg-2 lzma 4.43-14ubuntu2 man-db 2.6.0.2-3 msr-tools 1.2-3 netpbm 2:10.0-15 odbcinst1debian2 2.2.14p2-5ubuntu2 odbcinst 2.2.14p2-5ubuntu2 orbit2 1:2.14.19-0.1 printer-driver-c2esp 21-1 ptouch-driver 1.3-0ubuntu11 python-chameleon 2.6.1-1 python-iniparse 0.4-2.1 python-paramiko 1.7.7.1-2 python-prctl 1.1.1-1build1 python-support 1.0.14ubuntu2 qapt-batch 1.2.65-0ubuntu1 qt-at-spi 0.0~git20110628-0ubuntu2 rastertosag-gdi 0.1-0ubuntu3 rhythmbox 2.90.1~20111126.89c872b0-0ubuntu2 rhythmbox-plugin-cdrecorder 2.90.1~20111126.89c872b0-0ubuntu2 rhythmbox-plugins 2.90.1~20111126.89c872b0-0ubuntu2 safecat 1.13-1build1 samba-dsdb-modules 4.0.0~alpha17.dfsg2-1 setserial 2.17-46 sni-qt 0.2.5-0ubuntu3 ssh-import-id 2.6-0ubuntu1 thunderbird-gnome-support 9.0~b5+build1-0ubuntu1 tsclient 0.150-4ubuntu2 ttf-sazanami-gothic 20040629-8ubuntu1 ttf-umefont 434-1 ubuntuone-client-gnome 2.0.1-0ubuntu3 ubuntuone-couch 0.3.0-0ubuntu2 ureadahead 0.100.0-11 virtuoso-minimal 6.1.3+dfsg1-1ubuntu3 virtuoso-opensource-6.1-bin 6.1.3+dfsg1-1ubuntu3 virtuoso-opensource-6.1-common 6.1.3+dfsg1-1ubuntu3 winbind 2:3.5.11~dfsg-4ubuntu3 xz-lzma 5.1.1alpha+20110809-3
