QmlProfiler crashes after second Qt5 project has been profiled

Steps to reproduce:

• make sure you have a kit using Qt5 (I've used Qt5.1rc)
• create Qt Quick 2 UI from 'New file or project...'
• profile it (works as expected - inferior closes on pushing 'Stop profiling')
• create another Qt Quick 2 UI
• profile it (does not close on pushing 'Stop profiling')
• (I've now profiled it again without closing it before - this closes the old inferior, starts a new one)
• the last profiled inferior must stay open to force the crash in Creator (if you close the inferior manually before closing Creator everything seems to be fine)
• close Creator

Expected result:

• nothing bad happens

Current result:

• Creator crashes (see attached crash log from Mac)
