[pkg-otr-team] Bug#773321: irssi-plugin-otr segfaults unexpectedly

[Antoine Beaupré]

Package: irssi-plugin-otr
Version: 1.0.0-1~bpo70+1+b2
Severity: critical

the otr plugin is severly damaged, both in jessie and
wheezy-backports.

in wheezy, irssi completely crashes after i "/load otr". this is even
without the xmpp plugin loaded, so it's different from #499229.

In jessie, it seems that it segfaults only when the xmpp plugin is
loaded, but it's a different issue than #499229 - because in #499229
the segfault doesn't occur if the connexion fails, while now things
are even worse: the plugins simply can't be loaded at the same time at
all. So while this doesn't seem to affect jessie directly, there's
still a regression there as well.

Maybe the fix for #767103 was not the right one...
