Comment 4 for bug 443426

I found some news: segmentation fault should be caused by imported modules written in c.
Now, I don't know exactly which of the modules that we use can cause the seg fault.
It depends on the architecture (mine is amd_64), on the distro (mine is 9.04), and so on.
Anyway I'll be very glad to solve this bug, but I cannot reproduce it by myself when I want to debug it.
So it's a big problem, and I really don't know what to do.
