Comment 1 Bug Janitor Service 2023-02-19 09:20:25 UTC

A possibly relevant merge request was started @ https://invent.kde.org/sdk/lokalize/-/merge_requests/32

Comment 2 wojnilowicz 2023-02-19 09:34:21 UTC

1. The crash happens because code leaks memory in Lokalize and in Qt\KDE (See also bug #466062)
2. If Lokalize code would not leak memory then Edit->Find could be opened without a crash with a Ctrl+F shortcut
3. The proposed patch fixes the leak in Lokalize and works around the leak in Qt\KDE

Comment 3 wojnilowicz 2023-02-21 22:23:47 UTC
