You need to gdb python, not the script:

I was not able to come to some exact package which is causing this. I was iteratively creating clones of original channel and removing packages from it and checking if it still fails to export.

Export works, if I remove first 50 or last 50 packages for a clone. Channel have 101 packages. So the issue might be caused by some combination of packages in a channel.

Or, might there be some delayed taskomatic process fixing something when I'm testing it?

We did not have time for this one during Spacewalk 1.4 time frame. Mass moving to Spacewalk 1.5.
