Main navigation - my signals - submitted - deleting a signal crashes the app

[z-zafirov]

If a user deletes one of its signals, the app crashes on deletion and the signal remains active/visible

1. Login with account that has signals
2. Go to 'My signals' menu and tap to select a signal
3. Tap on the 'bin' icon to delete it

Expected result
Signal to be deleted

Actual result
The app crashes and the signal remains

Fixed in v5.3.2(78) - please confirm.
(Should not bug) may affect other actions (status change, new comment) in Signal Details screen when coming from My Signals instead of from the map - when possible please confirm those work, too.
