Please update OpenDict depends to wxwidgets2.8 - wxwidgets2.6 is no longer supported by upstream and will be removed from Debian, also wxwidgets3.0 is supposed to be out early next year.
Currently opendict depends on python-wxgtk2.6, however, the opendict.py code tells wxversion that it's also happy with 2.8, so this should be a painless change, see this line in /usr/share/opendict/opendict.py :
wxversion.select(["2.5", "2.6-unicode", "2.8-unicode"])
I've build latest OpenDict package with changed depends to python-wxgtk2.8 and didn't noticed any problems when using it. Anyone can download latest OpenDict package (uses python-wxgtk2.8) from official Baltix GNU/Linux repositories:
http://ftp.akl.lt/Linux/Baltix/Baltix-Ubuntu-packages/baltix-11/opendict/
(this package soon will be available also at ppa:baltix-members/ppa )
Changing opendict to use python-wxgtk2.8 would also fix bug #662077 (WxWidgets apps don't have menus) - currently only wxWidgets2.8 are patched to have menubar in Ubuntu 10.10 or newer.
Currently (while opendict uses python-wxgtk2.6) I'm forced to replace /usr/bin/opendict with attached script:
export UBUNTU_MENUPROXY=0
exec /usr/share/
