Sometimes when or after debugging, QtC turns some or all of my breakpoints in "unclaimed breakpoints". This means they do not break debugging anymore.

This can happens literally while stoping a working debug session and starting it again, without any other interaction with QtC or the debugee.

What's even worse is that once this happened, I cannot add any new breakpoints. They just go "unclaimed" immediately. I have to restart QtC to continue debugging. Not even this helps sometimes, so I have to resort to WinDBG or Visual Studio to do any further debugging.
