Debugger hangs when adding a disabled BP of type 'Break on data access at fixed address'

Steps to reproduce:

• create a simple project (I've chosen Qt GUI application)
• go to Debug view, right click into Breakpoints widget, Add Breakpoint...
• choose 'Break on data access at fixed address' as BP type
• choose an address (I've chosen an address taken from a former debug run as well as a pure fictional)
• let this BP disabled
• start debugging

Expected behaviour:

• gdb runs without problems

Current behaviour:

• gdb hangs and brings up a message box which asks to give gdb more time - you can give more time but gdb still hangs
