I upgraded to 2.1.5, and we have the same assertion failure, on the same mailbox:

I guess enabling core dumps is a good start, I'll do that, but has anyone seen this before?

1. doveconf -n output

2. Can you show the list of all mailbox names? Or especially the one that is causing this crash? (The raw backtrace indicates it happens during quota recalculation, which gets a list of all mailboxes, so it might not really be the same mailbox as what appears to be broken.)
