Now Playing freezes the app

If I play the song from Inbox, then move the album to Library and then go to Now Playing tab this causes the Error:

This makes sense - the folder is not there. However, the app stops responding.

so i am fully clear on what is going on, "D:\temp_music\[2004] Best Of Acoustic - Various Artitsts" was the folder the files resided in while located in the Inbox, and when you moved the files to the library they were reorganised to another folder due to auto-organise rules. One of the files that was moved was the playing track and you have auto-save for lyrics enabled.
Does that sound right?
did MB stop the playback when you moved the files?

[metabaron]

correct. I stopped the playback before moving the files to library.
