Package: centerim-utf8
Version: 4.22.10-1
Severity: important
Tags: patch
When I sign in to MSN centerim often segfaults.
After looking into the issue it seems to be due to a missing field in a
response from the MSN server.
args[5] here from notificationserver.cpp line ~200 will be undefined since
the <vector> only has 5 entries:
this->myNotificationServer()->externalCallbacks.gotNewReverseListEntry(this, \
args[4], decodeURL(args[5]));
This is because the MSN server is sometimes sending:
ADD 0 RL 0 [email protected]
Instead of this:
ADD 0 RL 0 [email protected] User%20Name
So my quick fix to this (without any knowledge on the MSN protocol) was to
copy [email protected] to args[5] and that way avoiding the segfault.
I'm attaching an patch that shows how I solved my issue.
