Comment 4 for bug 338765

I also have this error. I'm currently using bzr 2.3.3-3 with Bazaar Explorer 1.1.4 on WinXP (and Win7 32 Bit also tested).

What happened was this: I created a new checkout from within Bazaar Explorer in a directory which wasn't empty. This directory contains some similar named files, and so there are conflicts with adding files, which gave me 13 of this messages:

...
Conflict adding file changelog.txt. Moved existing file to changelog.txt.moved.
...

When I click on the resolve icon, I got this error message:

I have attached a sample. If you try to do a checkout from testrepo-fb\trunk to testrepo-fb-checkout, you will get this error.
