qlog: odd graph in qbzr trunk

[Alexander Belchenko]

Look at the graph of recent history of qbzr trunk. Expand revno.291, then expand revno.278.1.3. You'll see blue circle of one merged revision with minus sign inside it. Although this minus is unrelated to other merges. See attached screenshot.

When I click on that minus sign I get traceback in console:

Traceback (most recent call last):
  File "C:\work\Bazaar\plugins-repo\qbzr\lib\log.py", line 546, in changesList_mouseReleaseEvent
    newindex = self.changesModel.indexFromRevId(revision_id)
  File "C:\work\Bazaar\plugins-repo\qbzr\lib\logmodel.py", line 856, in indexFromRevId
    revindex = self.msri_index[self.revid_msri[revid]]
KeyError: 20

and expanded branch of revno.291 collapsed.
