Bug 1654

Claws Mail crashes when performing IMAP operations.  The crashes don't seem to be following any discernable pattern, other that when moving/copying/fetching messages between IMAP directories and accounts.  This began happening when I upgraded from version 3.3.1, which I installed from the Ubuntu repositories, to version 3.5.0, which I installed from the Launchpad repositories.

I'm running Xubuntu Linux version 8.04, kernel 2.6.24-19-generic
Backtrace from the latest crash follows:
