Segmentation fault problems

[Alain Spineux]

How long the system worked without problem before this ?
2.3.9 is very recent, what did you used before ?
What are the last chnage you did ?

A segfault is easyer to throbleshot, but need some work.
You need to find the source of the package, recompile it with debug
option enable, install it
and run it until a segfault append. Then explore the core dump to find
where the error append.
Are you ready ?

But dont forget to answer all my other question
