SUMMARY When going to System Settings->Application style->Gnome/GTK Application System Settings halts, then crashes. STEPS TO REPRODUCE 1. Open System Settings 2. Select Application Style 3. Click Gnome/GTK Application Style 4. Wait for crash (About 15 - 25 seconds) OBSERVED RESULT System Settings halt, then crashes after some seconds. EXPECTED RESULT To be able to select without crashing and change GTK themes. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Manjaro KDE (available in About System) KDE Plasma Version: 5.16.4 KDE Frameworks Version: 5.60.0 Qt Version: 5.13.0 ADDITIONAL INFORMATION Not sure if it's bad form but I have a Manjaro forum post looking for help troubleshooting as well as the output I'll paste here. https://forum.manjaro.org/t/glibc-error-in-kde-system-settings/96898 The output I paste here is updated today. I've updated Manjaro (On testing Branch) 6 times since it started happening. ---------------- 8/10/19 8:03 AM systemd-coredump Process 16944 (systemsettings5) of user 1000 dumped core.

Please let me know any other information you need. Thanks for your time.
Created attachment 122046 [details] A copy of the crash report from ksystemlog Also, added an attachment of the ksystemlog crash report.
Unfortunately the backtrace is worthless without debug symbols. :( We would need a backtrace that includes debug symbols.
Ok, I'll see about getting that a little later today. Thanks for the reply.
Well, I hope this is helpful. Bit of a Linux newb so I had to figure out how to get a backtrace that might be helpful. I used strace. I hope that's acceptable and I hope it has whatever symbols you need to track this down. I did try the gdb method listed on the arch wiki but I was obviously doing something wrong there. So it's kind of a big file. For whatever reason when strace is running systemsettings5 doesn't fully crash but just becomes unresponsive and needs to be killed. I let it run several minutes expecting it to disappear like it normally does. When it didn't I just killed it. ----------the file was to large to upload so I put it on google drive--------------- https://drive.google.com/open?id=1kIqv7DxbuJPndDBrJEdpz18a7iC6GqIV
Heh, thanks. In general the right approach here is to install the debugging symbols package that your distro provides. Unfortunately, Manjaro, being an Arch derivitive, doesn't provide debugging symbols at all. So the only remaining option is to compile the software from source with debug symbols, then run that, reproduce the crash, and generate the backtrace yourself with gdb. In the past I've advocated for disabling the automatic crash reporting functions entirely for Arch-based distros because the backtraces we get from them are not useful. :(
Doing all the compiling is a tad out of my expertise at the moment. I'm learning but it's probably safe to say that's trying to swim with sharks. Welp, I apologize for wasting your time then. It's rather frustrating that these tools aren't available on Arch/Manjaro systems. Thanks for your time. I guess we can call this closed as I can't really provide the info you need. :/
No problem. As a bug triager and developer, it's one of my frustrations with Arch-based systems, too.
