Comment 2 for bug 123589

narcan, is this really all the output you're getting? I also get the

** (.:9939): CRITICAL **: gtk_pizza_set_size: assertion `pizza != NULL' failed

but it is directly followed by

*** glibc detected *** vlc: munmap_chunk(): invalid pointer: 0xb2b93008 ***

which really seems to be the cause for the crash...
