qlog crash with Kubuntu Lucid

[Michele Tartara]

Since I updated my system to Kubuntu Lucid Beta1 (10.04), qlog just crashes as soon as it is started (without any parameter, just "bzr qlog") with the following dump:

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

Traceback (most recent call last):

The Qbzr and bzr release I'm using are those from Kubuntu's repositories.
