Beets keeps crashing if processing double files?


hey everyone,
first i wanna say thank you for this awesome tool! i got more than 1 000 000 files to process with beets and started to create a config…
i copy pasted some stuff into my conf and also add my own requirements to it…but somehow it seems to crash sometimes.
i looked then into the source folder and noticed double files cause some of these issues but it still crashes sometimes, heres one of these crashes

My config looks actually like this…
maybee there are just some uneeded copy paste errors?!

would love some help to optimize my config… ;D


Huh! This does look like a problem. Is it possible to reproduce the crash reliably? If so, can you please file a bug on the issue tracker with instructions to trigger the problem locally? Then we can look into a fix.


i can reproduce it, but the strange thing is: if i run it in -vv mode this error doesnt occure?!
even all the questions about album matches doesnt show up… why?
and in verbose mode there apear no cleaned up files in the music lib dir from beets


The verbose output can bury the importer prompts under a mountain of text. They’re there, but you may need to scroll up to find them.


sure it does, but shouldn’t it create the same output files as a normal run without verbose? and shouldn’t it crash at the the same point as it does like before?


Probably! That’s certainly strange if it doesn’t.


ok, so i was wrong, i deleted the files and started beets in verbose mode, just to see that some files where created…and then suddenly stoped with no error…
i looked at the files where the import stoped and found an “#” in one of the filenames…but deleting it didnt helped either,
stopped at the same point…
