Bug#512339: linux-image-2.6-amd64: Mplayer crash causes BUG: unable to handle kernel, NULL pointer dereference at 0000000000000000
Package: linux-image-2.6-amd64
Version: 2.6.26+17
Severity: important
An mplayer crash when playing specific files will trigger the kernel
error message that will be described. From that moment on, a range of
crashed/freezed processes can
be killed no more. Example of such unkillable processes:
29866 ? 00:00:00 kaffeine
4005 ? 00:00:00 gmplayer
4309 ? 00:00:00 mplayer
2491 ? 00:02:57 amarokapp <defunct>
4327 ? 00:00:03 vlc <defunct>
I mark this as important as processes like Kaffeine and Amarok can no
longer be started until a computer restart.
A file that makes MPlayer crash like that:
http://ruina.tam.cornell.edu/research/topics/bicycle_mechanics/JBike6_web_folder/JBike6_self_stable_files/bicycle_stability.mov
Playing this file will make other players crash, but not affecting the
kernel like that.
