Duplicated albums in music library

Hi,

I think there is a bug in the current nightly build of 7.9.0 - 1459489175.

Lots of albums - but not all - appear twice in the library.

I have been looking for a pattern: file types, m3u, cue files, etc. but none of these seem to be the issue.



On the other hand, a problem with scanning of album year seems to be fixed :-)
