Hi,
learn how to help yourself and later us (you did not tell us anything about your system).
Example: $ $ locate libatk-bridge /usr/lib/gtk-2.0/modules/libatk-bridge.so
Already had that installed and know that's the problem
$ rpm -qf /usr/lib/gtk-2.0/modules/libatk-bridge.so at-spi-1.30.1-1.fc13.i686
That's the problem though, knowing to use -qf. I'm using rawhide and this sort of problem can be down to many things or just plain user error.
Search Google: libatk-bridge : g_module_make_resident You will see that there is a problem reported in F14 already
Oddly, when I did that last night, it came up with nothing for rawhide.
TTFN
Paul
