out of the blue sab stop working and I can't get it started again. I tried upgrading from 0.6.8 to 0.7.0 but no luck there. In the Fedora log I get this:
Jun 25 19:08:56 localhost abrt[5454]: saved core dump of pid 5451 (/usr/bin/python) to /var/spool/abrt/ccpp-1340676535-5451.new/coredump (12038144 bytes)

Jun 25 19:08:56 localhost abrtd: Corrupted or bad crash /var/spool/abrt/ccpp-1340676535-5451 (res:4), deleting

When starting it doesn't get past this, constantly. Any ideas?

And what is the output of SABnzbd when you start it on the commandline?

[gjc1000]

I get this message when I use the command line:

$ ./SABnzbd.py
python: /builddir/build/BUILD/Python-2.7/Objects/dictobject.c:759: PyDict_SetItem: Assertion `value' failed.
Aborted (core dumped)

This clearly indicates a faulty Python interpreter.
It simply isn't possible to create a Python script that would
cause this kind of error, at least not when using a correct interpreter.

So:

If there is another Python version (2.5 or 2.6) on your system, try to run with that version.
If not, de-install and remove python, and do a fresh install.
