Crash when using diff

[Jian Jiao]

The branch was stored on my NAS using bazaar Windows version, when accessed from the ubuntu version on another computer, it appears all the files were modified, but it was not true. When I did 'diff', a crash happened.

bzr: ERROR: exceptions.AssertionError: get_next() called when there are no chars left

Update report: Error happens when I went back to Windows to open the project after that.

[Alexander Belchenko (bialix)]

based on traceback I say you have corrupted dirstate file. Why it so I can't say, but this is not bug in Bazaar Explorer per se, nor in QBzr.

[Jian Jiao (jj8431)]

Thanks Alex, It might be caused by the cross access by Windows and Linux. I'm not sure. What I'm worried about most is how to recover my previously logged versions.

[Martin Pool (mbp)]

Jian, you should be able to recover from this with 'bzr repair-workingtree'.

Hi Martin, I tried as you suggested form a command window in Windows, but still got similar error messages.
