Summary:                    asterisk random crashes: IMAP toolkit crash: Unlock
when not locked
Description: 
Asterisk crashes randomly. The system log always contains this message:

Oct 10 13:23:47 hermod asterisk: IMAP toolkit crash: Unlock when not
locked

Needless to say, this makes my wife very unhappy. :)

Asterisk-1.4.22 with zaptel-1.4.12.1. No local hacks.
Debian GNU/Linux 4.0 (fully updated); Linux kernel 2.6.21.5 (custom); on a
custom VIA Esther-based mini-box.
IMAP server is Mac OS X Server 10.5.5 (Cyrus IMAP).

Please let me know what else I should be providing. This IMAP library
error supposedly indicates a re-entry of threading bug in the caller, which
in this case would be asterisk...

And another IMAP abort, with a somewhat different traceback. This was
leaving an about 2:10 long message and letting it time out (5 seconds
quiet). See asterisk-2.gdb. Note that I just switched from imap-2006i to
imap-2007a (the new abort is with the 2007a version). Sadly, that doesn't
seem to have helped.

 The debug log leading up to this was

    -- Zap/2-1 is ringing
    -- Nobody picked up in 27000 ms
    -- Hungup 'Zap/2-1'
    -- Hungup 'Zap/1-1'
