Yade is a python script now, you have to run python in gdb instead and
give the script name as first argument to python inside the debugger
(equivalent to running "python /home/3S-LAB/jduriez/YADEdeb/bin/yade--
debug")

$ gdb /usr/bin/python
(gdb) run /home/3S-LAB/jduriez/YADEdeb/bin/yade--debug

Status in Yet Another Dynamic Engine: Incomplete

Bug description:
Since updates executed on 15/09/10, (from a long-time non updated state), I can not launch yade with qt4.

If I compile with 

PREFIX = '/home/3S-LAB/jduriez/YADE'
exclude = 'none'
features = 'gts,log4cxx,opengl,openmp,qt4,vtk'
version = 'trunk'
CXXFLAGS = []
SHCCFLAGS = ['-fPIC']

I get a segmentation fault at the launch : 
jduriez@c1solimara-l:~/YADE/bin$ ./yade-trunk
Welcome to Yade bzr2438
Erreur de segmentation

Whereas, if I compile with :

PREFIX = '/home/3S-LAB/jduriez/YADE'
exclude = 'none'
features = 'gts,log4cxx,opengl,openmp,vtk'
version = 'trunk'
CXXFLAGS = []
SHCCFLAGS = ['-fPIC']

I have no problem:
jduriez@c1solimara-l:~/YADE/bin$ ./yade-trunk-ssqt4
Welcome to Yade bzr2438
TCP python prompt on localhost:9000, auth cookie `aukesy'
XMLRPC info provider on http://localhost:21000
[[ ^L clears screen, ^U kills line. F8 plot. ]]

I'll try to compile on debug mode to have more information (not sure it is possible on my PC)
