Description Friedrich 2024-04-29 19:47:33 UTC 
SUMMARY
k3b always crashes while a self-burned Audio-CD is in my optical drive.
I've opened the CDs in dolphin and apparently the filenames are not UTF-8 encoded.
The crash doesn't happen with any of the non-selfburned CDs I have.

STEPS TO REPRODUCE
1. Run k3b
2. insert selfburned CD with weird text-encoding

OBSERVED RESULT
The software crashes.

EXPECTED RESULT
The software shouldn't crash.

SOFTWARE/OS VERSIONS
Fedora 40
KDE Plasma Version: 6.0.4
KDE Frameworks Version: 6.1.0 
Qt Version: 6.7.0
