[opensuse] Problem running monodevelop-0.15 under KDE

The monodevelop 0.12 that came with openSUSE 10.2 works fine under both GNOME and KDE; after adding the Mono repository for openSUSE 10.2, though, I experienced crashes when running monodevelop 0.15 on KDE. I notice, however, that running monodevelop as a different user works:

su - anotheruser monodevelop

surprisingly, as long as su - is used, monodevelop works (i.e. instead of anotheruser, it could have been any user, including the one currently logged in) Running monodevelop under GNOME, needless to say, works as well. The problem seems to involve GTK, leading me to suspect it's some theming problem. GTK-Qt, perhaps? Would appreciate any help. Meanwhile, I'll just have to su - to myself before running MD.
