Execution marker behaves different when interrupting (compared to gdb)

Steps to reproduce:

• create Qt Widget Application
• build it and start debugging
• when application is up and running hit 'Interrupt'

Current behavior:

• backtrace is listed correct
• execution marker points to the first entry of the backtrace (which is unreachable code)

Expected behavior (as it is when using gdb):

• execution marker points to the line 'return a.exec();' in main.cpp (this would be the first line inside the backtrace which would be printed in black instead of grey)
