Getting this error (running under PyCharm to get the log!):

> File “.\picard\album.py”, line 279, in \_finalize\_loading  
> self.\_new\_metadata.strip\_whitespace()  
> File “.\picard\metadata.py”, line 349, in strip\_whitespace  
> self.apply\_func(lambda s: s.strip())  
> File “.\picard\metadata.py”, line 334, in apply\_func  
> for key, values in self.rawitems():  
> RuntimeError: dictionary changed size during iteration

EDIT: crashes with 2.0.4dev1 and a very simple script: $set(newartists, %artists%)  
(and no plugins)

That’s good. Unfortunately I can’t test it until next week as I am away without my PC.

Fix was merged today. We’ll prolly release Picard 2.0.4 soon.
