Package: libkf5kiocore5 Version: 5.54.1-1 Severity: normal Tags: patch upstream
Dear Maintainer, in the last year I hit a few crashes with kate, without knowing how to reproduce the crash. Today I found this upstream reports [1] and several duplicates. With that information it was easy to reproduce the crash by just creating several nested folders in the save as dialog of okteta. It got fixed upstream in [2] and is included in upstream version 5.63.0. As this may affect all users of the KDE save as dialog, this might be considered for inclusion to stable? Kind regards, Bernhard [1] https://bugs.kde.org/show_bug.cgi?id=401916 https://bugs.kde.org/show_bug.cgi?id=411310 [2] https://cgit.kde.org/kio.git/commit/src/core/kcoredirlister.cpp?id=f539b17ceec2a8c7a453228b7db62a7919b849be -- System Information: Debian Release: 10.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-debug'), (500, 'proposed-updates'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-6-amd64 (SMP w/16 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE= (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libkf5kiocore5 depends on: ii libacl1 2.2.53-4 ii libc6 2.28-10 ii libkf5auth5 5.54.0-2 ii libkf5configcore5 5.54.0-1+deb10u1 ii libkf5coreaddons5 5.54.0-1 ii libkf5crash5 5.54.0-1 ii libkf5dbusaddons5 5.54.0-1 ii libkf5i18n5 5.54.0-1 ii libkf5service-bin 5.54.0-1 ii libkf5service5 5.54.0-1 ii libqt5core5a 5.11.3+dfsg1-1+deb10u1 ii libqt5dbus5 5.11.3+dfsg1-1+deb10u1 ii libqt5network5 5.11.3+dfsg1-1+deb10u1 ii libqt5xml5 5.11.3+dfsg1-1+deb10u1 ii libstdc++6 8.3.0-6 libkf5kiocore5 recommends no packages. libkf5kiocore5 suggests no packages. -- no debconf information
