Shows the hanged state of the program on meeting the condition

Description ulterno 2023-12-21 17:20:52 UTC 
Created attachment 164343 [details]
As you see, the forward slash I was typing in the position of the cursor is not shown. The application freezes before that.

SUMMARY
Type //abcd/ in directory picker dialogue address bar. Application hangs before showing the last character typed.

STEPS TO REPRODUCE
1. Open Kate
2. Click on "Open Folder..." button. (Can find it in Menubar->File or on Welcome screen)
3. In the Choose a Directory dialogue
 1. Empty the address bar
 2. Start typing with two forward slashes, then some alphanumeric character(s), then another forward slash.
 3. Alternatively, you might type something else and remove a character to reach the resultant string.
Alternative steps to reproduce:
- Use QFileDialog::getExistingDirectory(...) function and continue with Step 3 above or use provided code snippet.

OBSERVED RESULT
- The folder picker hangs and so does the application
- Only happens in case of folders and not in case of the file picker
- The completion drop down menu is stuck on top and stays there on hiding the frozen application
- Application can be exited externally
