Picard: rsgain fails with error code -6

[admiral-Guck]

Trying to calculate ReplayGain on albums or single tracks fails with the below traceback. Directly executing rsgain on the folders or files via the command line works fine.

plugin 1.7.1
rsgain 3.5.3

E: 03:33:42,596 util/thread.run:69: Traceback (most recent call last):

rsgain only returns 0 and 1, so we can conclude that rsgain is not being executed by the fact that the return code is -6. Is the path set correctly in the plugin settings? What happens when you type the path setting verbatim into your terminal?

[admiral-Guck]

which rsgain tells me /usr/bin/rsgain, which I put in the "Path to rsgain" setting. The same error persists.

rsgain works as expected from the terminal, with the full path or not.

Edit: turns out it's specific to one machine, so I suppose something's wonky with system python there.

@admiral-Guck how did you install Picard? And on what OS exactly?

[admiral-Guck]

Both machines are running manjaro and I installed Picard from the official repos using pamac.

Ok, thanks. Just wanted to make sure it is not installed with Snap or Flatpak and sandboxing getting into the way. Because there /usr/bin/ would be not your system location. Otherwise I have currently no good idea what might be happening on your machine, though. But it doesn't seem to be a rsgain issue.
