fedora 20 :: thunderbird segfault

[Adrian Sevcenco]

Hi! I have a very strange situation in which on an computer with fedora 20 (i have 2 desktops and only one have problems)
after some time (even if i start fresh and a leave it idle) a have a segfault. I tried even with a fresh .thunderbird directory with the complete elimination of extensions from the system .. 
from the gdb i see this :

(gdb) run
Starting program: /usr/lib64/thunderbird/thunderbird 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".

    import gdb.backtrace
ImportError: No module named backtrace

a lot of new threads ..

Program received signal SIGSEGV, Segmentation fault.
0x000000324e60b91a in elf_machine_rela (reloc=0x7fffa3526a70, reloc=0x7fffa3526a70, skip_ifunc=0, reloc_addr_arg=0x7fffa3d30e90, version=0x180, sym=0x7fffa349b450, map=0x7fffb63f1000) at ../sysdeps/x86_64/dl-machine.h:276
276           struct link_map *sym_map = RESOLVE_MAP (&sym, version, r_type);

the puzzling thing is that the both machine are more or less identical, with the same fedora 20 with almost the same packages installed...
also, what is that "Corrupted shared library list"? is there anything i can do?

Thanks!
Adrian
