Bug 407171 – media-video/vlc-1.1.13 crashed when trying to disable xscreensaver

• Status: RESOLVED FIXED
• Product: Gentoo Linux

emerge --info vlc

When vlc starts to play a film and disables the screen saver, it crashes with an access violation.  It does not when the "disable screensaver" is not set.  This is independent from a screensaver running or not.

please give a backtrace of a crash as described in:
http://www.gentoo.org/proj/en/qa/backtraces.xml

and reopen, thx

It is within the nvidia drivers :-/ (x11-drivers/nvidia-drivers-295.20-r1) and it seems to happen when xdg-screensaver is called.  If i call xdg-screensaver from a shell within xterm, it doesn't crash, however.

The crash does not occur with x11-drivers/nvidia-drivers-290.10-r2.

[Comment 4 Alexis Ballier 2012-03-20 09:25:54 UTC]

could you please try again with vlc-2.0.1 ? there's an abi fix wrt nvidia drivers there

[Comment 5 Thomas 2012-03-22 12:11:10 UTC]

vlc 2.0.1 and nvidia-drivers 295.20-r1 seem to cooperate.  I only tested this with a few clips from the internet, however.

[Comment 6 Alexis Ballier 2012-03-22 12:21:06 UTC]

good, thanks
closing then since 2.0.1 will go stable soon wrt bug #408881
