qlog exceptions.KeyError: (1318, 12)

[Stas Kalashnikov]

When I try to close revision 1318.13.1 node (look at the screenshot), I get the following exception:

bzr: ERROR: exceptions.KeyError: (1318, 12)

Do you have a branch publicly available we could test on?

> Do you have a branch publicly available we could test on?
The source code is not available publicly and I my try to recreate the branch structure in a test repo failed.

[Stas Kalashnikov (halega)]

I have repeated this bug in a test repository. It's branch colocated repository. Start qlog in trunk and open "Bugfix32" node (rev 15) and then "Version 2.1" node (rev 2.2.1). And then when I try to close "Version 2.1" node I get an exception.
