installation of keepass2 / mono breaks icons in nautilus / on desktop

i attached another screenshot, this time the desktop.

the same problem occurs on my ubuntu workstation at work which is x86_64 installation with a different nvidia graphic adapter (quadro)

if anyone needs more information, i'd be happy to provide.
with this particular issue, i have no idea where to start digging. suggestions are welcome.

this is interesting, I don't see how keepass or any of its dependencies could cause that.

does sudo update-mime-database /usr/share/mime fix the issue?
maybe try removing /usr/share/mime/packages/keepass2.xml and then update the database again.
(reinstall it with sudo apt-get install --reinstall keepass2)

thanks for the suggestion, i'll give it a try.

i suspect the culprit is one of the mono dependencies of keepass. reason
is, keepass does not use the native window manager, it's interface looks
very windows-like (as in ms windows).

i can usually "fix" the issue by purging keepass2. just removing
keepass2 does not seem to fix the problem.

i just can't seem to reproduce this reliably.
the problem also occurs after removing (not purging) keepass2. the update-mime-database command does not help but killing X and logging in again seems to provide a temporary fix.

i attached a copy of my .xsession-errors.
right around "DEBUG 2012-02-23 19:18:48" when i logged in, the problem occurred. there are a lot of warnings about icons, which could be related to my problem.

btw, when installed keepass2 via apt-get, one of the lines on the console reads:

Processing triggers for hicolor-icon-theme ...

what command is that?

further info: i'm using the ambiance theme

its possible that its not keepass fault but some general problem when the desktop stuff gets updated.
Try installing and purging different packages that install into /usr/share/mime

dpkg -S /usr/share/mime give you a list of installed ones, on my system:
brasero-common, keepass2, apport, shared-mime-info, obconf, nautilus-data, libreoffice-common, opera, kile, gnash-common, software-properties-gtk, tomboy, kate-data, virtualbox-qt, monodevelop, vinagre, kde-runtime-data, grsync, kdelibs5-data, banshee: /usr/share/mime

updating the icons is done with sudo update-icon-caches /usr/share/icons/hicolor/
