offlineimap crashes processing folder named 'tmp'

[Kevin Kennedy]

Binary package hint: offlineimap

I'm using offlineimap 6.2.0+nmu2ubuntu1 in Ubuntu 10.04.1 LTS to backup up my gmail mailboxes. Offlineimap successfully backed up all mailbox folders including "tmp" on the first run. On subsequent runs, it crashed until I renamed the folder "tmp" to "tmp_"

Here is the error:
