can't open an album if it contains double quotes (")

I can reproduce this on the most recent trunk on FreeBSD.
Exaile does not generate debug output or a traceback related to the problem. How can I diagnose where it happens?

I believe I found where this happens.
In xlgui/panel/collection.py there is the class member CollectionPanel.get_selected_tracks() which calls CollectionPanel._find_tracks() for the given iterator. This function generates the search criterion by calling CollectionPanel.get_node_search_terms() for the iterator. This constructs a single string containing the search criteria by doing:
return " ".join(queries)

This results in a returned string like (example for a song containing a double quote)
u'discnumber=="0" tracknumber=="3" title=="Some song (12" Remix)" album=="Some album" artist=="Some artist"'

And if this string is passed later into trax.TracksMatcher(), it will generate a matcher object with matcher.content=u'Some song (12' instead of u'Some song (12" Remix)'
This does not match any existing track in the database and no track is appended to the playlist.

Shouldn't CollectionPanel.get_node_search_terms() return a dictionary defining the search criteria instead of one single string? Then we wouldn't have to worry about certain characters.

should be fixed in trunk/2877.
