Description
Steps to reproduce:
- Create a new Qt Quick application
- Switch to a Profile build
- Switch to Callgrind in the debugger combobox
- Start analysing
- 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:
