hmm, i'm not sure whether i understand this.
- does it mean, that Pd/Gem _always_ crashes (when opening a window, or 
closing a window, or...)
- does it mean that Pd/Gem crashes as soon as you use anything which 
involves pixes (coming from e.g. [pix_image], [pix_film] and/or [pix_video])
- does it mean that Pd/Gem crashes as soon as you use [pix_video]?

in the first case, try running "glxgears" from the cmd-line and see what 
it tells you (it is part of the mesa-utils patckage)

in the last case, try running Pd/Gem from the cmdline and see what it 
tells you before crashing.
try adding "-stderr" to also catch the messages to the Pd-console
try adding "-verbose" to get additional messages.
