Application: systemsettings5 (5.11.4) Qt Version: 5.10.0 Frameworks Version: 5.41.0 Operating System: Linux 4.9.73-1-lts x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: Everytime I go to type into the system settings application it crashes. After every system restart, it seems to crash on the first character, then after restarting the system settings application enough times, it may wait until I hit enter. Other times the search will almost go through then crash. I find it does not usually save what I have changed even if I have applied the changes before the crash. The crash can be reproduced every time. -- Backtrace: Application: System Settings (systemsettings5), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

Hi, the status of this bug ("resolved upstream") seems very confusing to me as the potential fix obviously is still under discussion (/review process). Apart from that, thanks for your great work and efforts...
RESOLVED UPSTREAM doesn't necessarily mean that the crash itself is already resolved, but rather that there's nothing we can do here in this bug report, so from a KDE perspective, it is resolved here and remaining work is tracked upstream, in Qt. That patch should *eventually* make it in, not to worry.

Created attachment 112231 [details] Yet another backtrace. Hi, still crashing (using QT 5.10.1), see attached backtrace. @Nate: Sure, that it's fixed in QT 5.10.0? My system: - Current Debian testing - KDE Plasma Version: 5.12.4 - KDE Frameworks Version: 5.44.0 - QT Version: 5.10.1 - Kernel Version: 4.15.0-2-amd64 I understand that in the strict sense this is not a "KDE bug" (most likely), but it still leads to the fact, that Plasma itself feels buggy... ...that's kinda sad as these problems are there for so long now. Systemsettings crashes here and then since the introduction of it's new layout. IMHO it would have been a better decision _not_ to provide, or at at least _not_ to default to the new layout... as long as these problems are around. Earlier, "Icon View" has never crashed for me. Don't get me wrong. I'm a fan of the "Sidebar View", but I prefer stability. (Perhaps, if QT is not capable of fixing this, one should think about a workaround. I.e. implement the new feature(s) via an other way/strategy [using older mechanisms]?) Regards, Gerhard

The Qt patch (https://codereview.qt-project.org/#/c/217395) is marked as included in Qt 5.9 and 5.11, but not 5.10. I can still reproduce this issue in Fedora 28, with 5.10.1 and systemsettings 5.12.5. Would it be possible to request Qt to cherry-pick this fix on 5.10?
There will be no Qt 5.10 update; it is not a LTS release.
