Comment 1 for bug 1464933

Thanks for this bug report. This is certainly not good - I haven't seen it myself though before.

To better analyze what the problem is would it be important to have a debug log file.

For this you can configure Diodon to automatically write its debug log to your home folder.

You have to go to Startup Applications through the Dash and change the command of the Diodon entry to the following:
bash -c "G_MESSAGES_DEBUG=all setsid /usr/bin/diodon &>~/diodon_debug.log"

Once you have logged in and out of Unity Diodon will now start automatically and write its log file to ~/diodon_debug.log.

Keep now Diodon running till the error as you explained it occurs - when it does get a copy of the diodon_debug.log and attach it to this bug report.

Hope this will help to see what is going on. Thanks.
