Summary:                    Crash with malformed (invalid) exten in
extensions.conf
Description: 
I set up a context like the following:

[main]
switch => Realtime/main at extensions

exten => 101,Meetme()

Asterisk will start successfully with that dialplan, and throw a bunch of
this warning:
[Dec 10 15:51:40] WARNING[13234]: pbx.c:2578 pbx_find_extension: Maximum
PBX stack exceeded

Once its up, if I 'reload', Asterisk crashes.  If I run through the same
scenario with a properly formatted extension (with a priority), I have no
problems.

OS is Ubuntu 10.04.

Attached is a gdb of the core dump with 'bt' and 'bt full'.
