Error opening a playlist (file format could not be determined) but it is a playlist created by Audacious itself

[fabioforall]

I am using command line to operate Audacious (I need to create a script, so I am testing) and I need to open a playlist.
I give the command:

~ $ Audacious "/path/to/playlist/playlist.pls"

and I receive the following error:

Error playing file:///path/to/playlist/playlist.pls:
The file format could not be determined. The format may be unsupported, or a necessary plugin may not be installed/enabled.

However:

1. if i import the playlist from the gui, it is imported without errors
2. the playlist has been exported by Audacious itself

On further testing, if I cd to the directory where the playlists are stored, and issue the command:

~ $ Audacious playlist.pls

the command is executed without errors.

I suspect a problem with text encoding, because non-european characters are present in the playlist.

I am running Audacious 4.2
I am under Raspbian 12

playlist file attached

disco.pls.zip

Better show/attach the full output of:
audacious -V playlist.pls

The attached playlist contains files in multiple file formats, such as MP3, M4A, FLAC. Both the playlist format ".pls" as well as the individual audio file formats require a corresponding plug-in to be installed and available.
