#73 sgain becomes None

[Hugo G.]

Recently (after an upgrade, I use Manjaro which is based on aArch) I' ve starte to get this error in IDJC:

Traceback (most recent call last):
  File "/usr/lib/idjc/site-packages/idjc/playergui.py", line 2711, in cb_toggle
    self.handle_play_button(widget, widget.get_active())
  File "/usr/lib/idjc/site-packages/idjc/playergui.py", line 1547, in handle_play_button
    if self.player_startup():
  File "/usr/lib/idjc/site-packages/idjc/playergui.py", line 1653, in player_startup
    self.gain = float(sgain)
ValueError: could not convert string to float: None

This happens whenever I select an MP3 file to play from the playlist or when a new file has to play in any playlist. The player stops and I cannot start it, however, I can seek to +1 seconds and everythin plays normally.

I' ve done a workaround changing the code to

        try:
                self.gain = float(sgain)
        except ValueError:
                self.gain = 0.0;

But I have no idea what's going on. I asume this has to do with applying ReplayGain when playing a file. Any ideas where I should start troubleshooting? I' m on 0.8.14

Thanks,

Hugo G.

Can you make one of those mp3 files avaliable to me for testing?

[Magnus Holmgren]

I have the same problem. It happens with all MP3 files. The code where the exception occurs was introduced in commit 7b713e ("Loudness metadata now migrates properly from 0.8.8."), but that was 2½ years ago and I had been using newer versions for a long time before this bug appeared. I suspect something has changed in the library used to read MP3 metadata. I'm using Debian testing (Stretch). If you aren't yourself, you can see which version of other packages idjc uses on https://packages.debian.org/stretch/idjc

I have reproduced the bug after installing the latest version of mutagen.

[Stephen Fairchild]

It appears to be fixed now.

If it's already fixed upstream, the AUR package idjc-git should contain the
fix. It's the new version of Mutagen that's causing the problem for people
in rolling distros or in Unstable.
