I added one more assert, but I doubt that catches this:

This really looks like memory corruption, but since it could be anywhere
in the code it's pretty difficult to find where without running via
valgrind or similar.

Can you figure out if you can reproduce it with X features but not with
X-1 features? Like with/without quota enabled, or with/without some IMAP
commands in your tests?
