Start from the command line and see what warnings/errors you get.
Warning: any GTK application is likely to spew so many uninterpretable
warnings you'll think you have cat'ted core dump.

Well, no, I wouldn't expect your monitor to suddenly morph into a bus
guide complete with 5-octaves higher than normal voice and a little
flag, to be honest.  What do you mean by "not lead anywhere"?  Text of
misleading error messages would be really nice, maybe someone has seen
them before.  (Maybe the author of the confusing error message is
watching.  Wouldn't that be cool?!)

Any OS upgrades recently?  What are your SELinux and kernel capability
settings?
