qlog: Crashes with 'NoneType' object is not iterable

[Gary van der Merwe]

Not sure what I was doing to cause this, but I got this crash in qlog:

bzr: ERROR: exceptions.TypeError: 'NoneType' object is not iterable

Traceback (most recent call last):
  File "/home/garyvdm/.bazaar/plugins/qbzr/lib/util.py", line 1018, in decorate
    run_in_loading_queue(f, *args, **kargs)
  File "/home/garyvdm/.bazaar/plugins/qbzr/lib/util.py", line 1030, in run_in_loading_queue
    f(*args, **kargs)
  File "/home/garyvdm/.bazaar/plugins/qbzr/lib/uifactory.py", line 32, in decorate
    r = f(*args, **kargs)
  File "/home/garyvdm/.bazaar/plugins/qbzr/lib/log.py", line 516, in load_delta
    repos = [gp.get_revid_branch(revid).repository for revid in revids]
TypeError: 'NoneType' object is not iterable

looking at the traceback, it would hint that the 'revids' value was None.
