A nested progress bar was not 'finished' correctly

I receive the above error on the BitlBee bug tracking system when viewing ​http://bugs.bitlbee.org/bitlbee/changeset/197

The BTS uses version 0.10.3dev

This is the Python Traceback:

Btw, This Trac uses BZR as version control.

This is most likely a bug in the TracBzr plugin. Please contact its author regarding this error.
