I run a bleeding edge pre-release Fedora on the main laptop, and yesterday's update ended with this:

VLC media player 0.8.6b Janus

***MEMORY-WARNING***: [3884]: GSlice: g_thread_init() must be called before all other GLib functions; memory corruption due to late invocation of g_thread_init() has been detected; this program is likely to crash, leak or unexpectedly abort soon...
*** glibc detected *** vlc: free(): invalid pointer: 0x00000000010abc50 ***

Looks like Glib (glib2) people are trying to force applications' hands in 2.13.6-1.fc8.

Contingency plans are being put in effect and regular anime watching is to resume soon.

UPDATE: Fixed by glib2-2.13.7-2.fc8 and wxGTK-2.8.4-4.fc8.
