Kdenlive freezes after importing a sound file

I am using Kdenlive 19.08.0 on Tumbleweed. Importing and working with video files works as expected (i am able to cut them, play them back (even with sound), scrub through the timeline). But when I try to import any standalone sound file, that is not a part of a video file, Kdenlive freezes and writes the following into the error output:

/////////// starting to add bin clips
/////////// found list (QUrl("file:///home/user/lmms/projects/sicilian4.wav"))
/////////// creatclipsfromlist (QUrl("file:///home/user/lmms/projects/sicilian4.wav")) true "-1"

Kdenlive then stops responding, I am even not able to close it using the “X” button and I have to kill the process to close it. Here is the full log: https://pastebin.com/rr54tpDQ

I will be very thankful for any ideas how to fix this.

It does say wrong clip type crazy as this may sound see what happens if you change the .wav to a .mp3 worst that can happen it’ll still freeze or won’t copy.
