Dolphin segfaults whenever I open my music folder

This is more of an annoyance than a problem, but whenever I open my music folder in the dolphin file manager, the Dr.Konqi notification pops up telling me kdeinit has segfaulted. How do I fix this?

Application: kdeinit5 (kdeinit5), signal: Segmentation fault

I am not a KDE/dolphin expert. But it looks like the crash has to do with thumbnails. May be one thumbnail in the cache is corrupt or the thumbnail creation process crashes with one particular music file.

Can you try with a different graphics filemanager, like thunar or nemo? Do they show the directory incl. thumbnails?

You could also try to delete the thumbnail cache. But I dont know where that dolphin puts that.

I second that one :upside_down_face:

~/.cache/thumbnails

Then reboot Dolphin and try enter that dir again

Thanks for the help. That did not fix it. What other things may I be able to try? The nautilus file manager does not have any issues when opening the same directory.

Well…not sure
I think then it needs to be reported upstream :pensive:

Don’t use the Dolphin - but I wonder if it freaks on some of the filenames that are endemic on Music folders? I’d look for parentheses () and tildes` and even single quotes in bad places or odd numbers. It can be a nightmare handling some of Linux’s allowable filenames! (especially some of those specially constructed to be ‘just’ legal elsewhere)

Might not be it - but worth checking - could even be only one!
