Also seeing a crash in Simple-scan also with segmentation fault if that helps.
Comment 7 TraceyC 2025-04-02 19:15:02 UTC
Thanks for the backtrace. Unfortunately it's missing some  debug symbols for the following lines that we need to figure out exactly what's going wrong:


                #5  0x00007f3e305ecfed n/a (breeze6.so + 0x76fed)
                #6  0x00007f3e3ad388f4 n/a (libQt6Core.so.6 + 0x3388f4)

Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window and getting a new backtrace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this. Thanks again!

That's likely a different crash with a different cause. If Dr Konqui crash reporter comes up, please use it to create a new bug report. Otherwise, you can create a new report and get another backtrace manually like you did for this report.

eopkg search cant find breeze6.so or libQt6Core.so.6 symbols. Also coredumpctl no longer sees the crash trace only Simple Scan trace is listed. I need some help here.

> eopkg search cant find breeze6.so or libQt6Core.so.6 symbols. 

With eopkg, I've found the easiest way to find debug packages is to do a search for a keyword and grep for "dbg" similar to this:

eopkg sr breeze | grep dbg
breeze-icons-dbginfo         - Debug symbols for breeze-icons
breeze-dbginfo               - Debug symbols for breeze

So then you'd install breeze-dbginfo 
For libQt6Core for instance:

❯ eopkg sr --name qt6 | grep dbg

That gives a long list of things, but this is the one you want

qt6-base-dbginfo               - Debug symbols for qt6-base


. Also

Unfortunately, without a better backtrace, we won't be able to investigate where in the code the problem is. You can try:
1. See if there's still a file in /var/lib/systemd/coredump for dolphin
2. It might be easier to try to reproduce the crash and get the backtrace from that (after installing the debug packages)

There is a file in Systemd/coredump for Dolphin what do I do to process it. Also have successfully installed the debug symbols.

The file is a .zst and tried extracting it and open with crash process viewer but doesn't work.

It's not necessary to extract the zst file. If you open the Crash Process Viewer, it will show all the crash logs on your system. Click on the most recent one for Dolphin, copy the information to the clipboard and then paste it into a comment in this report.

Screentshot of Crash Viewer after opening .zst file

I tried that but as you can see from the attachment the crash viewer is empty

I see what you mean in your screenshot. Did you open the Crash Viewer first or try to open the file?

Used 'Open with' then selected all installed programs then selected crash viewer. The crash viewer opened on its own has been empty for a couple of days now. According to time stamp the dolphin archive file is from Monday which would be correct.

The crash reporter is meant to be opened first. Close it out and re-open it. That should make it re-read the list of crashes. Then open the most recent entry for Dolphin.

Still doesn't work no crashes listed and .zst opens with ark so removed that from default applications and still get a blank window as per screenshot.
Comment 18 TraceyC 2025-04-03 23:20:44 UTC
I'm confused why just opening Crashed Processes Viewer results in a blank window, since there are crash dumps.
Can I ask you to reproduce the crash and get a new crash dump?

Unfortunately after reboot I am unable to reproduce the crash. I have checked my other plasma machines and only one is populated and that is a VM which has a fairly fresh install of Solus and it shows a crash way back in January. 

The dir for the crash logs has about 8 entries for the machine that crashed but none show in crashed processes viewer, looks like a bug with the viewer.
