Debugging on iOS broken

Steps to reproduce:

• create a Qt Widget Application from template
• add a QPushButton and connect the clicked() signal with a slot
• set breakpoint into the slot for the QPushButton-click
• start debugging (on iOS device)
• wait for application and debugger being ready (takes a bit)
• touch the QPushButton to trigger the signal
• wait for the marker on the breakpoint to appear (and check the debug log that there's no more data fetching ongoing - takes some time)
• hit 'Continue'
• wait some time until the debugger seems to be ready again
  • instead of state 'Running' the app seems to have stopped again ('Continue' button is enabled again, state label says 'Stopped')
  • marker for location of execution is not displayed
• hit 'Continue' again
  • state label changes to 'Resume request failed - process still running.'
  • buttons and menu items for debugger interaction are greyed out/disabled
• touch QPushButton again
  • marker re-appears, but state label stays the same and buttons/menu items for debugging stay disabled

Note: I cannot attach the debug log actually (it's about 17MB and max is 10MB - so I'll crop out some irrelevant stuff to get it smaller and attach it later)
