segfault on muc join

[p5n]

I am using Arch Linux and following versions:

spectrum2 2.0.3-5 libpurple 2.12.0-2 purple-mattermost-git v1.1.r89.g4524538-1

Private messages looks working but transport segfaults on MUC join:

(I've tried to use name as an id but it is also NULL, line 4011 is mine but result is the same on original sources)

PS: It was from spectrum2 transport From pidgin MUC looks working

Latest (2683ee186f7b5186be6c604f0a2ccf32afa66448) does not segfault but it looks like that this plugin does not work with spectrum2. When I join channel it passes just channel name. Then it fails to split it in mm_chat_info_defaults() using channel name as team-id.

May be it is because of only roomlist information passed up and only roomlist info can be used by xmpp clients.
