Crash (probably on disconnect?) about irssi-xmpp

[cdidier]

As g_strdup simply returns NULL on NULL pointer, so it seems that the string is not '\0' terminated and strdup is reading past the end of the string.
This means that for some reason channel->get_join_data(CHANNEL(channel)) doesn't return a valid string (in the save_channels function).

[ailin-nemui]

the list contains some odd values like 0x23,0x1b,... so something seems to go entirely wrong -- this is not a valid memory address for storing of a string. (or I am misreading the dump)

Seems it's the GSList itself that's bad - my latest crash was because src->channel_list->next was invalid (data was a valid pointer, but a garbage string)
