Description Freek de Kruijf 2023-10-24 10:38:03 UTC 
Application: lokalize (23.08.2)

Qt Version: 5.15.11
Frameworks Version: 5.111.0
Operating System: Linux 6.5.6-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.8 [KCrashBackend]

-- Information about the crash:
I edited several plurals without problems and the last one stayed fuzzy but was ok, so I used Ctrl+U to make ok. At that moment lokalize crashed.

The reporter is unsure if this crash is reproducible.

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

More crashes in copyToBaseCatalog Łukasz?
Comment 2 wojnilowicz 2023-10-25 16:21:51 UTC 
I did as reported in "Information about the crash" (trying different corner cases) and cannot reproduce the crash.

Feel free to reopen this report when you will be able to reproduce the crash and provide more details.

lokalize (23.08.2) using Qt 5.15.11

Busy editing .../nl/messages/krita/krita.po in plural element. Left single allone, was OK, and tried to enter %1 in front of plural and to change single word in plural word, but crashed already when entering %.
