Bazaar Explorer crashes during Branch operation

[David Roberts]

To recreate:

Create an empty Win32 directory.

Open that directory with BE as a virtual repo.

Initialise a plain branch in the previously empty directory (= virtual repo)

create a single minimal test file in that branch and commit it.

From the virtual repo viewer pane, select the newly populated branch, select BRANCH (bottom right), and
branch to a second location at the same level within the virtual repo. Decline the option to create a
shared repo.

The branch operation appears to proceed normally, then throws a windows error dialog box which states
"Friendly distributed version control system has encountered a problem and needs to close. We are sorry for the inconvenience."
The 'more information' relates to an error in bzr.exe, ModName: qtgui4.dll

This is the logging for the commit and branch -

So, it seems to be the re-opening of the new branch that fails, not the branching as such.

Re-running BE, re-entering the virtual repo and re-trying the Branch operation to a new destination in the same location
SUCEEDS without error. (Also, the 'failed' branch appears to be intact and usable.)

This is with BE 0.10.0-dev [r326] and Bazaar 2.1.0b3 installed from the setup.exe Win32 installer. It also occured
with the BE 0.9.0 code bundled with that installer. QBzr is 0.16.0

This problem does not seem to be reproducable with bzr-2.1.0rc1 and explorer 1.0.0dev [r395]

My guess is that this may have been the segfault/freeze bug. I'll mark it as a duplicate. Please undo that if you think otherwise and can make it happen again.
