You can report this problem to Bazaar's developers by running
    apport-bug /var/crash/bzr.1026.2010-08-29T22:02.crash
if a bug-reporting window does not automatically appear.

[Alexander Belchenko (bialix)]

You have a problem with bzr-search plugin which (I believe) tried to update the search database on each commit.
As workaround, try to commit as:
bzr --no-plugins commit ...
or temporarly disable(delete) search plugin.

It looks like bzr-search needs to handle when there are 0 total_revisions:

>>> import math
>>> math.log(0, 2)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: math domain error

Probably this only happens on the first commit into a repository.

Hi,

I get similar problem during commit, push or pull.
The problem appear with upgrade version 2.2.0-1~bazaar4~lucid1
when I revert bazaar to version 2.1.1-1 I get no more problem
