Download a binary with debug symbols

You must download a binary for the corresponding KDE applications with debug icon support from, e.g.

  1. download umbrello-master-xxx-windows-msvc2017_64-cl.7z
  2. download umbrello-master-xxx-windows-msvc2017_64-cl-dbg.7z
  3. Unpack both archives to the same location.

Download a debugger

  1. Download SDK installer from
  2. Start winsdksetzup, select "Download the Windows Software Development Kit ...." and press "Next".
  3. Uncheck all except "Debugging Tools for Windows x64".
  4. After the download is complete, enter the download directory and run "X64 Debuggers And Tools-x64_en-us.msi" from the Installers subdirectory.
  5. Then search the Start menu for "WinDbg (X64)" and run it.
  6. Select "File"->"Open Executable" from the application menu and select the main executable file you unpacked before, e.g. <unpack-root>\bin\umbrello5.exe.
  7. Select ""Debug"->"Go" to start the application. In case of a crash it will stop automatically.

Get the back trace

  1. Select "View"->"Processes and Threads" from the application menu and select the main thread (id 000) if not already selected.
  2. Select "View"->"Callstack" to see the backtrace.
  3. Press "Source" in the call stack windows to see the source information.
  4. To save the call stack to the clipboard, press the icon on the left side of the Close button in the window title.
  5. Open a new bugs at and paste the clipboard content into that bug.

Note: Normally KF5 applications use DrKonqi to automatically generate a backtrace after a crash
