      Description

      Steps to reproduce:

      1. Create a new Qt Quick application
      2. Switch to a Profile build
      3. Switch to Callgrind in the debugger combobox
      4. Start analysing
      5. Once the application has run for a couple of seconds, click "Stop" (as documented here) - it will say "Parsing finished, no data" and won't give any profiling results.

      Application output:
