OpenOffice 2.1 creates Gnome menu templates in /usr/share/applications. They
keep the same filenames as the version 2.0 templates, which is fine.
However, the "Exec" line in the new files (specifically writer, the others are
similar) is:
Exec=openoffice.org-2.1 -writer %U
No file called "openoffice.org-2.1" is created however -- the executable is
still the same as version 2.0: "ooffice2"
The line on my other computer which still has 2.0 reads:
Exec=ooffice2 -writer %U
Changing the menu template on 2.1 to match that on 2.0 fixes the problem.
