Normal When Picard loads a .webp file on Linux, it is mistakenly trated as a RIFF/AV file.
This is traced to picard/formats/registry.py:guess_format, where for some reason the results has WAVFile with a score of 1.
Breakpoint set in guess_format right before the if results block.
I have not observed this behavior for other formats (jpg/png).
The side effect of this behavior is that cover art may appear as damaged files in the UI, and exceptions are logged to the console.
