I meant the assert itself (or change it to an i_error("recent flag
bug")). Although few clients really use recent flags, so it probably
doesn't matter much what you do. :)

Anyway I'll try to look into why it's crashing. But it doesn't look like
I can reproduce this with my imaptest tool, since it's been running for
2,5 hours now without this crash.

You could also see if this patch happens to help (probably not):
