Crashed Impress stack trace from KDE

When trying to add an audio file to an empty presentation, Impress almost instantly crashes.

Steps to reproduce:
1. Run Impress
2. Insert an audio file (tested with .wav and .mp3)

Workarounds:
Setting SAL_USE_VCLPLUGIN=gtk3 fixes the problem - audio can be embedded.

Versions affected:
Still: 25.8.4-1
Fresh: 26.2.0-2, 25.8.4-3

System info:
OS: Arch Linux (updated just before filing a bug)
GUI: KDE
LO UI: kf6 (cairo + wayland)
gstreamer installed (gstreamer, gst-plugins-base, gst-plugins-good, gst-plugins-bad, gst-plugins-ugly, gst-libav)

Stack trace:
Relevant thread only (libreoffice-impress-audio-crash-stack-trace.txt)

Other notable info:
The same audio clip embedded in Writer does not cause a crash.

Please attach an audio example that make LibreOffice crash at adding it to the presentation.

Please test with Menu>Help>Restart in Safe Mode.

Please paste here the information in Menu>Help>About LibreOffice.

(There is an icon in the center to copy the information).
