deleting from apps list via context menu crashes BTT

If you remove an app from the apps list on the left via context menu (right click, delete), BTT crashes. Removing apps from the apps list by clicking the trashcan icon on the bottom does not crash.

It's 100% reproducible for me. Add any app to the list and then right-click delete it, instant crash.
Tested on two different machines, one is 10.5.7 and the other is 11.0.1, with stable and latest alpha 3.508 (1646). (The attached log is not from latest alpha though.)
