Description Angel Montes 2022-12-01 01:50:22 UTC 
Application: filelight (22.08.3)

Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.10-arch2-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
It has been a while since last time I used filelight. The last time I remember filelight opening it was not showing all the disks and partitions I had, if I recall correctly it was showing only one partition.

I have multiple hard drives on my PC but I'm not sure if it has anything to do with it. I tried reinstalling but so far no luck.

The crash can be reproduced every time.

-- Backtrace:
Application: Filelight (filelight), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}

When does it crash? Startup?
Comment 2 Angel Montes 2022-12-02 01:44:05 UTC 
Hi Harald,

Yeah, whenever I try to start the application it keeps crashing. It also shows the same behavior if I try to restart filelight.
Comment 3 Harald Sitter 2022-12-04 00:13:08 UTC 
It reads and sounds a lot like your QML cache has gone off the rails. If you move ~/.cache out of the way does filelight start?
Comment 4 Angel Montes 2022-12-04 19:22:11 UTC 
I'm not sure I can remove the .cache folder, as there's a lot of stuff there.

I did find this path for qml: /home/aamm19/.cache/krunner/qmlcache/

Should I remove that one and give it another go?
Comment 5 Harald Sitter 2022-12-04 19:32:22 UTC 
I said move it out of the way not remove it. After testing you can move it back
Comment 6 Angel Montes 2022-12-04 22:11:01 UTC 
Okay, that was a misunderstanding on my part.

i renamed the .cache folder to backup.cache, re-executed filelight and it's working properly now.
Comment 7 Harald Sitter 2022-12-04 23:26:16 UTC 
If you want to keep your cache (shouldn't really be necessary) then you'll need to find the qmlcache file related to the crash, or just remove all of them you can find - there may also be some in Qt related folders. The bug here is probably somewhere deep in Qt, I'd ask you to file an upstream bug report but realistically I don't see that progressing very far without being reproducible on Qt 6 :(
Comment 8 Angel Montes 2022-12-05 00:03:52 UTC 
Thanks for the help so far Harald,

I found and deleted the qmlcache on /home/user/.cache/KDE/filelight/ and filelight and it is working properly now.

As for how reproductibe this might be on Qt6, I can't say for sure, given that I don't know what was the source of the issue itself either :(

I'll just leave this post for future references for whoever needs it.

Thank you!
