Journal fails to load if a single activity icon is broken

[sascha_silbe]

If a single activity icon is broken, Journal will die on an uncaught GError in jarabe.journal.journaltoolbox.refresh_filters() while filling the "what" filter combo box.

Test case:

1. Install the attached bundle.
2. Start the just installed HelloWorldBrokenIcon activity using the Activities list view (the Ring / Spiral view will not work because of the broken icon).
3. Restart Sugar.
4. Verify that the Journal starts up.

HelloWorld activity with broken icon

Ok, I installed your activity, and did start Sugar. The activity icon is not displayable in the activity list of home view and the log does show the error you describing:

I still can use the Journal fine, it did not die for me. Anything else you need to do to make it die?

logs when the Journal dies (you need to start the broken activity once and then start Sugar again)

Updated test case. You need to run the activity and restart Sugar in order to trigger the bug.
