I can't reproduce the crash on demand, unfortunately. It happens every so often. Search for messages from me previously on the list (2018-11-22) was when I posted previous backtraces (although they seemed to be useless). Last time it was during UID SEARCH that the error was happening.

I'll go through the trouble of building a debug version again and turn on core dumps, but I doubt I am going to get something new or super useful again :-(
