Debugger: Hitting Soft Asserts when loading core file

Steps to reproduce:

• create a simple application which will result in a segfault, run it to have a core file at hand
• trigger 'Debug' -> 'Start Debugging' -> 'Load Core File...'
• configure the dialog as necessary

Current result:

• works, but displays a Soft Assert on the cmdline

  ATTEMPTING TO QUEUE COMMAND  "info shared" IN INAPPROPRIATE STATE EngineRunRequested
  ATTEMPTING TO QUEUE COMMAND  "p 5" IN INAPPROPRIATE STATE EngineRunRequested
  SOFT ASSERT: "m_currentIndex < m_stackFrames.size()" in file stackhandler.cpp, line 165
  

Expected result:

• no output on the cmdline
