It's been > 5 hours and I haven't seen this, sorry if you get it twice.
It seems a number of GTK+ progs in 8.2 are compiled with a dependency on libxeno.so and complain when you start them (GAIM, Galeon, and others.) A quick search on Google reveals that libxeno.so is part of the Xenophilia GTK+ themes engine. Looking at the flat list in rpmdrake, neither Xenophilia nor libxeno seem to be included in the distro. Where can I get this library?
