debugging - Is there a bug inside GroupStyle HidesIfEmpty? -

i have windows phone 8.1 winrt application. using semanticzoom + listview combination display grouped list through collectionviewsource. when remove items groups (which observablecollections) and start putting items these empty groups debugger breaks , shows "agip.*" @ point reads disable_xaml_generated_break_on_unhandled_exception; used happen while reason not know app exits , debugging stops without error message; why cannot remember exact filename.

i have 2 questions:

1) how can debugger work 1 time again i.e. display "agip.*" page , not silently quit?

2) trial , error managed track downwards cause of changing <listview.groupstyle><groupstyle hidesifempty="true" <listview.groupstyle><groupstyle hidesifempty="false". , voila app works without problems. bug in winrt?

ps: can accomplish hidesifempty behaviour binding grouping header visibility .items.count through converter that's not issue here.
