Reproducible X Server crash in v1.5.3 on Intel Mobile 945GME

[Mike Fleetwood]

Hi,

I have a reproducible X Server crash in X.Org X Server 1.5.3 on my
netbook with an Intel Mobile 945GME graphics card.  When playing an
ASF video full screen in xine and using [Alt]-[Tab] to switch to
another task causes the X Server to crash.  Other types of video files
such as MP4, MOV and AVI don't trigger a crash.  Also when xine is
playing the ASF video in a window it also doesn't trigger a crash.

Wondering if this is a known bug?  Whether to raise a bugzilla entry?
How to go about debugging this further.  (I have never compiled or
debugged an X Server before so I will take some guiding).
