You can report this problem to Bazaar's developers by running
    apport-bug /var/crash/bzr.1000.2011-08-30T19:22.crash
if a bug-reporting window does not automatically appear.

The recipe used is:
# bzr-builder format 0.3 deb-version 0.1.0+{date}-0
lp:~telepathy-kde/telepathy-kde/master-telepathy-kde-approver
nest-part packaging lp:~telepathy-kde/telepathy-kde/telepathy-kde-approver debian debian

python -c 'from bzrlib.plugins.builder.cmds import get_maintainer; print get_maintainer()' yields
