Hi Pawel (again 😀)

Thanks a lot for your help! I added workaround in my scope (used QSet to
preserve uniqueness of content) and now it works well!
Seems that you should write this somewhere in documentation, because
someone else can get such crash.
My bad - I didn't try to switch-off sources one by one.

Again, huge thanks!
