The crash is occurring cleaning up a GsApp object after a plugin operation has completed. I've looked down code-paths to try and find what could have corrupted the object but not finding anything standing out. It seems possible this might be due to multiple threads accessing data. In 3.22 a lock was added to the data, but this is a major change that can't be backported. It smells like the sort of issue where - have multiple threads - threads interacting badly - add locks - problem goes away (but root cause not found).

I investigated the possibility of backporting gnome-software 3.22 to Xenial but the dependencies are too new to be able to do that.
