Bug#433117: Rapid scrolling between desktop panels while running Totem crashes gdm with "gdm_slave_xioerror_handler: Fatal X error"

[Fred Korz]

Package: gdm
Version: 2.18.2-1
Severity: important

This gdm restart problem seems to straddle gdm and xine packages.  I
never have this problem when Totem isn't playing something, regardless
of how fast I switch panels, which suggests an interaction.

If you can classify it squarely as a xine problem, please route this
to that package's maintainer(s).

When running Totem with an mpeg2 (25 fps video + audio) playing, if
one switches desktop panel quickly, *boom*.  Back to the greeting
screen with all applications closed (hurrah - signals propagated and
apps did their best when the display manager choked).

I've also had this misbehavior with streaming content in iceweasel via
the plugin.

I am running latest "testing" version (per "apt-get update" + dry run
of dist upgrade).  Don't know why system information includes "sid"
since neither "sid" nor "unstable" are in /etc/apt/sources.list.

Reportbug noted there was a newer version of gdm, but wouldn't that
pull me into unstable ("sid")?

Lossage from syslog bracketing the latest gdm immolation were:
