I agree that fixing the bug is better than failing better, so long as the bug
gets fixed :)

The commit still fails for me.  I get a UnicodeDecodeError in testament.py.  If
I set $BZR_HOME to point to an empty directory (so as to ignore my ~/.bazaar
settings), then the commit succeeds but I get a UnicodeEncodeError in
dirstate.py during branch.

I think the reason for the difference is that I have “create_signatures =
always” in my bazaar.conf.

In case you're wondering, I'm using Ubuntu (Intrepid, i.e. 8.10), so my system
Python is also 2.5.  My LANG=en_AU.UTF-8.  In addition to changing BZR_HOME I
also used --no-plugins.
