Thanks for the report. I just pushed something that I believe should fix the crash—can you please verify that it does?

Now It doesn't fail but neither I see the thumbnail in GNOME nautilus 3.10.1.
I have tested the plugin directly:

$ beet -vv thumbnails 'lana del rey'
user configuration: /home/simon/.config/beets/config.yaml
data directory: /home/simon/.config/beets
plugin paths: 
Sending event: pluginload
artresizer: method is (2, (6, 7, 7))
thumbnails: using IM to write metadata
thumbnails: using GIO to compute URIs
library database: /home/simon/.beets/musiclibrary.blb
library directory: /home/simon/Música
Sending event: library_opened
thumbnails: using IM to write metadata
thumbnails: using GIO to compute URIs
thumbnails: generating thumbnail for Lana Del Rey - Honeymoon
thumbnails: album Lana Del Rey - Honeymoon has no art
Sending event: cli_exit

But there is a .jpg file in folder named cover.jpg:

01 - Honeymoon.mp3
02 - Music to Watch Boys To.mp3
03 - Terrence Loves You.mp3
04 - God Knows I Tried.mp3
05 - High by the Beach.mp3
06 - Freak.mp3
07 - Art Deco.mp3
08 - Burnt Norton (interlude).mp3
09 - Religion.mp3
10 - Salvatore.mp3
11 - The Blackest Day.mp3
12 - 24.mp3
13 - Swan Song.mp3
14 - Don’t Let Me Be Misunderstood.mp3

If you can do more investigation to figure out exactly what's going wrong, @simonbcn, please open a new bug. For example, a useful bug report might look like:

I use the file manager X, which wants thumbnails to be generated in format Y (see this link to the documentation). The thumbnails plugin seems to do Z instead. If I manually make some change, then I can make X recognize the thumbnail. So I think the plugin needs to do that in order to work for my setup.
