Subsequent tries seems to just be ignored (status bar does not update and the folder is not moved). When restarting Shredder (Thunderbird) I can move two more folders successfully but the 3rd+ tries will fail. Error Console is blank. Reproducible: Always Steps to Reproduce: 1. Start Shredder having an IMAP account configured 2. Create a subfolder called First 3. Create a subfolder called Second 4. Create a subfolder called Third 5. Create a subfolder called Parent 6. Move First to Parent. Will successfully be moved 7. Move Second to Parent. Will successfully be moved 8. Move Third to Parent. This and subsequent moves fail Actual Results: Third and subsequent folder moves fail. Expected Results: Same behaviour as first and second folder move.

Can you provide a protocol log? <http://wiki.mozilla.org/MailNews:Logging>

Third folder move try leaves no trail in the log.

that means we didn't try, which means it's not an imap protocol bug.

perhaps the copy service got stalled.
