[SR-Users] IMC module - #join to private room crashes kamailio

[Ozren Lapcevic]

Hi,

there is a bug in IMC module that crashes Kamailio.

Here is the scenario: One user (pero at abc.hr) creates private chat room (
chat-999 at abc.hr). Other user (oz at abc.hr) tries to join the
chat-999 at abc.hrby sending #join. Kamailio crashes at that point. Here
is the log:

Best regards,
Ozren
