Hi Kester,

 Thank you very much for helping me to catch the bug! :)

  Hihi, nice trick ! Really ! That way, my box crashes more slowly X-)...
  (only kidding...)

  Ok, I did it...

  The result (the beginnig of the lanc_povanim226_11.py, comments
  stripped)

   --> import sys
       import Blender
       import Blender.Draw
       from Blender.Draw import *
       import Blender.BGL
       from Blender.BGL import *
       
       import pdb
       
       L=sys.path
       ls=Blender.Get('filename')
       ls=Blender.sys.dirname(ls)

 The last command executed BEFORE the machine hangs is marked with a
 "-->" as pdb it did...

 If I entered a "step" into the debugger then, there was no
 "switching" of the arrow, no output and time was just enough to
 switch to another desktop of IceWM...then the machine freezes (which
 is no result of _Ice_WM ;)

 And: _Everything_ freezes.

 It /seems/ that "import Blender" is at least a part of the problem.

 Reboot....

 The next experiment I did was to start with a fresh scene and a fresh
 script window. I only entered "import Blender".....ALT-P....._NO_
 freeze. It was executed without harming my Linux box.

 Interesting that the way my box crashes is not a "sudden death" in
 sense of the "speed" for example segfaults happen normally. It
 "feels" more like a lock which is caused by something fastly
 "growing" -- as someone would eat up all CPU power in hundredth of a
 second.

 And the screen always remains ok. No "colored crash" or something
 like that.

 Sorry for that prosa, but I am neither a pci guru nor a python
 guru....

 Keep hacking and 
 kind regards,
 Meino
