Bug 469919

Application: spectacle (23.04.1)

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 5.19.0-41-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
SUMMARY
If a user closes Spectacle by pressing Enter, Shift+Enter, or Ctrl+Enter, the application closes and notification "A screenshot was saved to your clipboard" appears. However, if Enter, Shift+Enter, or Ctrl+Enter was pressed during text input, then the next launch of Spectacle crashes.


STEPS TO REPRODUCE
1. Launch "Capture Rectangular Region" (default shortcut is Meta+Shift+Print)
2. Click on the button for the "Text" annotation tool
3. Click somewhere to start the "Text" annotation tool
4. Press button "Enter" on the keyboard (or Shift+Enter, or Ctrl+Enter)
5. Launch "Capture Rectangular Region" a second time

OBSERVED RESULT
After step 3, notification "A screenshot was saved to your clipboard" appears.
After step 5, notification about Spectacle crashing appears.

I will also attach a screen recording demostrating the crash.

EXPECTED RESULT
The crash after step 5 shouldn't happen. Maybe the behavior after step 4 should be changed as well (e.g. to just close the text input instead of closing Spectacle).
