There is no test-case, the backtrace doesn't give any context, the xsession-errors are in Russian, and I've reported instability of IMAP sessions due to network interruptions (also going online/offline directly inside Claws Mail) upstream before. Until there is news of improvements in Claws Mail IMAP support, better restart Claws Mail more frequently in case of networking troubles. If you know a specific test-case and like to assist the developers in tracking down the problem, consider contacting them at ttp://www.claws-mail.org/
