[Mirco Müller (macslow)]

Juan, can you please update to current notify-osd 0.9.24 and see if that crasher remains?

[Mirco Müller (macslow)]

Juan, can you also attach the file ~/.cache/notify-osd.log _after_ the crash occured so we'll be able to see what exactly did get send to notify-osd. Also please provide the exact thing you did causing the crash, if you can do so. Or log onto the IRC-server irc.freedesktop.org, channel #ubuntu-devel and ping me (MacSlow), so we can try to force this crasher together.

[Mirco Müller (macslow)]

From a conversation I had with Juan on IRC and via emesene (not crashing my notify-osd :) one should start looking at the libnotify-plugin of it. It's part of emesene upstream. Right now there's no deterministic way to force the crash to occur.

[Mirco Müller (macslow)]

The plugin as emesene itself are written in Python. The plugins code is in emesene-1.5/plugins_base/NotifyOsdImproved.py so if anybody wants to join the bug-hunt... be my guest.

GerryC, could you stop opening random and wrong tasks on launchpad?
