Symbol lookup error: /usr/lib/libKMediaSession.so

Description:

After upgrading my system yesterday (and again just now), Kasts fails to start:

$ kasts
symbol lookup error: /usr/lib/libKMediaSession.so: undefined symbol: _ZN6QAudio13convertVolumeEfNS_11VolumeScaleES0_, version Qt_6

Additional info:

  • package version(s): 25.08.2-1
  • config and/or log files: -
  • link to upstream bug report, if any: -

The same thing observed with ldd:

$ ldd --function-relocs /usr/bin/kasts
[successful lines redacted]
undefined symbol: _ZN6QAudio13convertVolumeEfNS_11VolumeScaleES0_, version Qt_6 (/usr/lib/libKMediaSession.so)

Steps to reproduce:

Launching the app from desktop or CLI without arguments.
