I just did an apt-get update; apt-get upgrade and I can no longer reproduce the problem either.

So let's watch it and see what's up: (this function is entered twice, once when the app is launched, once when I open the plugin's page. This is the latter.)

I'm guessing it's being freed by a callback from another thread, but I don't know what I need to do in order to debug further.
