[Gnump3d-users] Can't find <song name>.m3u after upgrade

[Tim Wunder]

Hi,
Just upgraded from 2.5b to 2.7. Now, when I try to play a song, I get an
error:
" The requested file <filename>.m3u couldn't be found. Please try
returning to the index."

All my MP3s display, and I can navigate directories. But if I click on
the MP3 to play it, I get the error message.

The config file is the same as I'd been using, and nothing is jumping
out at me as a mis-configuration.

I've executed
# gnump3d-index -stats
Total number of songs: 78
Total size of archive: 254Mb (266416378 bytes)
Total playlength     : 0 days, 4 hours, 37 mins 41 seconds

which was wrong, so I did:
# gnump3d-index
# gnump3d-index -stats
Total number of songs: 425
Total size of archive: 1.6Gb (1730109322 bytes)
Total playlength     : 1 days, 1 hours, 57 mins 8 seconds

and it seems to be OK:
# gnump3d --background
Tag Cache initialized, 425 entries

But the problem persists.
I've had gnump3d working since version 1.something, what am I missing?

Thanks,
Tim
