I have the same problem, but only after upgrading from Breezy to Dapper a few months ago. The most anoying thing is when starting gnome, gnome- setting-daemon keeps on restarting thus changing the the theme as fast as it can. For now I just renamed liboil-0.3.so.0*. No more problem exept that every gstreamer apps does not work.
Here's the output of running totem on the command line: OIL: ERROR liboiltest.c 359: oil_test_check_impl(): illegal instruction in mt19937_i386_mmx_3 Illegal instruction Output of gnome-setting-daemon: �OIL: ERROR liboiltest.c 359: oil_test_check_impl(): illegal instruction in mt19937_i386_mmx_3 Illegal instruction I tryed installing older version from debian, same problem. I tryed recompiling the .deb, same problem. I traced in liboil, found the code that does the illegal instruction, but did not want to start debuging assembly, so I stopped there. I'll find that function again and will post it, but for now I must get to work. Here's a post on a french forum where a bunch of other people have the same problem: http://forum.ubuntu-fr.org/viewtopic.php?pid=367249 Kristian -- installing Ubuntu or updating packages hangs at config libgstreamer https://launchpad.net/bugs/41248 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
