As the summary says i'm experiencing some random crashes when i access a folder of my imap account (gmail imap).

I've seen this behaviour at least from two previous releases, that is 3.7.9 and 3.7.10

I've finally been able to compile from source enabling debug traces. Below I attach a debug trace when it crashed.
