If I select the settings button in the analyzer annotation in the editor:
"Show diagnostic settings"

the settings panel pops up:

and after about 20 seconds Qt Creator crashes.
No further click needed.
Qt Creator crashes immediately if I click on the "Diagnostic Configuration" combobox.
Qt Cretor does not crash, when I use the menu to open the options window.
