Sven,

good observation, thanks. I did what you suggested and it looks to me like the 
problem comes out of libxul. NS_RegistryGetFactory () is calling itself many 
times before the crash. I see more details, I tried to run with libxul0d-dbg, 
but I failed. Has anybody an idea why that is or could I do something else?

Thanks,
Rainer
