Comment 3 for bug 1374965

The bug appears to be a crash when unloading the vdpau library, either via a dl_close() or dl_fini() call. It also affects any application using the vdpau library, such as mplayer and mythfrontend.

A backtrace from mythfrontend follows:

I have observed the same with mplayer. nvidia-settings crashes in a call to dl_close().
