Comment 15 for bug 637202

Not sure if the service is shutting down, or if an application is shutting down or flickers on the bus and as the application-service-appstore tries do dispose the reference it fails and crashes. That's from the analysis of crashers going through application_removed_cb

It may not fix the problem for specific app indicators, but being extra cautious when dealing with object references along the application_removed_cb path may help and prevent the whole service from crashing.

I think that's a worthwhile audit to perform on the existence codebase (natty) and see if a backport can then be provided to desktop for an sru candidate that reporters here could test.
