Thanks for the bug report, and sorry for not getting back to you
earlier. I've tried to reproduce this locally for the last couple of
days, but have failed. I'm using a slightly newer version of bzr-git,
but there have been no changes to the SQL side of things in a long
time. 

Cloning debbugs works fine here. Unity still fails, but later in the
process and with different errors than you're getting.

I wonder if the glibc realloc error is related - I'm not seeing that.

If you have a sid install around, it would be great if you could try
git-remote-bzr on that with the current Python package there.

If you're looking for a small bzr branch to test with, I usually use
bzr-stats ("lp:bzr-stats").

Cheers,

Jelmer
