Bug 452424

Application: lokalize (21.12.3)

Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.17.1-arch1-1 x86_64
Windowing System: X11
Distribution: EndeavourOS
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
Immediately after completing the translation of a gettext message, I tried to save the .po file, but Lokalize crashed. After restarting it, it obviously shows the recently changed gettext messages from an internal backup, and I'm able to save my work.

I'm unsure if this crash is really reproducible. Well, such crashes happen very often, but I don't know whether for the same reason. But especially with very big files (> 1000 gettext messages), Lokalize is very sensitive. Then it is almost impossible to work without saving the file after each translated message.

-- Backtrace:
Application: Lokalize (lokalize), signal: Segmentation fault
