asterisk users - Nov 2007 - Chanspy attaching to a caller ID entry?

Hi folks,

We have a very rare problem with Asterisk 1.2 where Chanspy reports the
following:
 Oct 31 19:53:29 NOTICE[10490] app_chanspy.c: Attaching SIP/105-48807010

 to "University of Florida" <3523922908>

The last line results in a full on crash without a core dump. This is a
SIP phone going through an extension setting CID but before a Dial(),
and another SIP phone ChanSpy'ing them. We have ChanSpy set to only spy
on bridged channels as well.

Has anyone seen a bug like this? We often top 10,000 calls a month, and
this only happens maybe twice a year. We're switching to 1.4 soon, but
just curious :)
