Summary:                    [patch] Asterisk crashes randomly on mISDN
RELEASE_COMPLETE
Description: 
I experienced random crashes on an asterisk when an Call over mISDN is hung
up.

The backtrace for the crash always looked similar (see attachment), so i
check the source.
I noticed that there is a check for ch->need_queue_hangup, but it would
just print a message and continue executing the rest of the code.
The fix seems really trivial, but tests show that the asterisk didn't
crash anymore.

I tested the patch in Asterisk 1.4.40-rc2, but I didn't helped.

I have the segfaults since 1.4.37-rc1, that's why I suspect this change of
chan_misdn.c:
