Error displaying local repository history

[Henrik Binggl]

When displaying history/log information about a local repository Bazaar Explorer crashes with the following traceback:

bzr: ERROR: exceptions.AttributeError: 'NoneType' object has no attribute 'style'

Traceback (most recent call last):
  File "/usr/lib/python2.6/site-packages/bzrlib/plugins/qbzr/lib/revtreeview.py", line 193, in paint
    style = widget.style()
AttributeError: 'NoneType' object has no attribute 'style'
