QComboBox newly crashes when calling `addItem()`

[davecotter]

Tested on Mac / Sonoma. Not tested on Windows/Linux
worked fine with Qt 6.6.0
fails with 6.6.1

can you reproduce this? easy steps:

• open "standard dialogs" example project (comes with Qt Creator)
• configure and run
• in running app, select "File Dialogs" tab
• check the box "Do not use native dialog"
• click "Get existing directory"
• <--- crash, see screen shot

if this is a real bug, i've reported it here. please upvote this bug.
