I have seen a lot of similar backtraces from IMAP crashes, but I am only using POP3.  I've also found this backtrace here [1], unrelated to the bug report it is attached to.

[1] https://bugs.kde.org/show_bug.cgi?id=176688#c17

Other potentially useful info:
* I have filters set up, so that some mail coming into the inbox is automatically moved elsewhere.  It doesn't look like I received any message when the crash occurred, though.
* It is possible that I had a search folder open when I last closed Kontact/KMail.  But they don't seem to remain open when KMail is restarted.

Will update bug report if I manage to reproduce.
