Bug Description

Binary package hint: vlc

Whilst playing a dvd in vlc I let the computer goto suspend (s2ram) i believe the dvd was in fullscreen at this time, upon opening the lid of the laptop (and thus returning from sleep) vlc had immediately crashed.
running ubuntu 10.04, with the latest updates as of 11th March.
running vlc version 1.0.5
system is a laptop which has an nvidia 7300gt running proprietary nvidia drivers version 195.36.08

note: having trouble reproducing this problem, i tried lauching the same dvd in fullscreen and manually pressing sleep on the laptop - then resuming and vlc still appears to be working correctly.

Considering the backtrace, this is a reentrancy problem in Xlib.
