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).
