I've reproduced a problem with Fedora6 linux. The reason why behaviour
can differ is that sometimes python interpreter itself contains
reference to libgcc_s.so (where _Unwind_GetIP is defined), but sometimes
- not.

Obviously we must add such a reference to our client library. Will do it
soon. As a fast help LD_PRELOAD can be used.
