Bug Description

When clicking the onboard indicator for the first time (after starting onboard), it can cause a crash of unity-panel-service. I never got crashes of unity-panel-service in connection with other indicators or applications, so I suppose it is something specific to the way how onboard creates its indicator.

Apport is regularly collecting the information for this crash, but then it quietly disappears, without telling me whether the crash was automatically reported and to where. Unfortunately I don't have any references / bug report numbers etc. but I have a file _usr_lib_unity_unity-panel-service.1000.crash (13MB) that apport apparently created (I don't which format it is). I was hoping there is a chance someone here could find out more than when I report it to unity, because it happens very specifically when using onboard. How can I get more debug info, or is the crash file of any help?

Ubuntu 14.10 64bit
onboard 1.1.0+1949-0ppa1~utopic
unity 7.3.1+14.10.20141016-0ubuntu1

You should be able to file another bug report with your crash file:
$ ubuntu-bug /var/log/_usr_lib_unity_unity-panel-service.1000.crash
If that worked you may want to duplicate this bug to the new one.

From what I can tell the crash seems to happen in libatk-bridge-2.0, see attachment. I ran
$ sudo gdb -p $(pidof unity-panel-service) -batch -ex 'c' -ex 'bt full'
then restarted Onboard and clicked the panel once. It doesn't always happen right away, but if I keep trying it will eventually. There might be a race with accessibles appearing/disappearing at the wrong time. I'm not sure if we can influence this from Onboard's side, but I'm going to experiment a bit.
