Description
In certain cases, when opening the profiler directly from the welcome screen (which doesn't make much sense but can happen if you misclick) qtcreator crashes with the following backtrace:

The backtrace is not very verbose as I haven't been able to reproduce the effect with a debug build, yet, nor was I able to figure out the exact environment parameters necessary to trigger it. In my current test case it's 100% reproducible, though.
