This problem is duplicated Issue 0010439 (from Applications/app_mixmonitor - I make error - Category is the same), but Severity and Reproducibility is not correct.

Seems like in the
==> module channel.c (1456)

(1456)if (option_debug)
(1457)    ast_log(LOG_DEBUG, "Spy %s removed from channel %s\n", spy->type, chan->name);

==>
values spy->type or chan->name is not valid at the process time.
The problem demands detailed research.
