Thank you for the report! I am fairly confident this is actually a duplicate of https://bugs.kde.org/show_bug.cgi?id=486468 and caused by a bug somewhere in phonon-vlc/vlc/pipewire (the wayland error is a symptom, not a cause), and the same crash might happen with e.g. dragonplayer, too.

Could you try running
gdb amarok
run
* and after the amarok crashes, type in gdb console: *
backtrace

some examples in the linked bug report. Most probably the output will be something like
Thread 1 "amarok" received signal SIGSEGV, Segmentation fault.

Thanks for the rapid reply! - here is my backtrace - no mention of pipewire - it appears to have chock on taglib...

Thank you for the response! Indeed, not quite exactly the same crash, that's interesting. However, seems to happen inside phonon-vlc backend, so likely not directly related to Amarok. Could you try playing the same track with dragonplayer and seeing if it crashes there, too?

Apologies for the delay - drgaonplayer works fine...

Okay, thank you for testing. Which distribution are you using, what kind of file are you trying to play? (local file? format?) I might try reproducing at some point.

The above was all tested on debian trixie - for other reasons I'm now on bookworm so can't do any more testing for the moment - sorry.

Ok, that's fine. As Debian packages are generally known to work, probably something related to your specific system and audio configuration. When (if) you encounter this again, we can continue to try to pinpoint it.
