bzr qlog crash when repo has been updated from SVN and the refresh button is pressed

[Scott Gibson]

I am using:
Bazaar (bzr) 2.2.2
  Python interpreter: c:\Program Files\Bazaar\python26.dll 2.6.4
  Python standard library: c:\Program Files\Bazaar\lib\library.zip
  Platform: Windows-XP-5.1.2600-SP3
  bzrlib: c:\Program Files\Bazaar\lib\library.zip\bzrlib

I have a repository that was branched from an SVN repository. The steps to reproduce are:

1) bzr qlog filename.pl
2) bzr pull (to retrieve updates from the SVN repository)
3) press the Refresh button in the qlog window
4) the error below is given

bzr: ERROR: exceptions.IndexError: list index out of range

I should also add that this example is when the file viewed by bzr qlog has been updated as a result of the bzr pull command. I can close the qlog windows and open again in order to view the full log details once again. Thanks.

I've done quite a bit of bug fixes for qlog refresh in trunk, which is not yet released. I possible, please will you test if you have this bug with trunk.

@Scott: do you still have this problem with bzr 2.3.1 and qbzr 0.20.1?

[Scott Gibson (wsgibson)]

The fix works for me. Thanks!
