squatter segfaulting

[Stephan76]

Hi,
with cyrus imapd 2.5.10 I started seeing crashes of squatter a couple of nights ago. The issue is 100% reprodicable and always occurs while working on the same mailbox. I ran reconstruct -G -r over the mailbox which made some corrections but the issue with squatter persists. I ran gdb:

I've just edited the original post to format the gdb output as "code", so that github doesn't try to parse it as markdown.

Is there any hope to resolve this ? It still occurs in 2.5.11.
