To trace your problem you need to debug kernel... as it is kernel level 
crash.
Try ask for help in kernel.org  newsgroups.

from your logs:
Pid: 24319, comm: imap Tainted: P U 2.6.16.21-0.8-smp #1

this line means - kernel is "tainted": 
P - A module with a Proprietary license has been loaded
U - An Unsupported module has been loaded, i.e. a module which is not supported by Novell (SuSE specific flag)

[ see: https://secure-support.novell.com/KanisaPlatform/Publishing/250/3582750_f.SAL_Public.html ]

Try unload propertary and unsupported modules ; then run imaptest again.
