Core was generated by `/usr/cyrus-2.4.6/bin/squatter -C /etc/cyrus-ugent/conf/mail12/imapd.conf -s -i'. Program terminated with signal 7, Bus error.

I've nailed it down to a specific mailbox:

I'm looking at it :)

I'm going to leave this one for 'future'. First I need to see what's wrong with the specific squatter file!

Tuning this right down - the file can certainly kill squatter on 2.4.6, and doesn't on 2.4.8 - but I don't think it's because we've fixed anything - more that the memory layout is slightly different and it's trashing something else. Squatter is nasty nasty code :(
