It seems to be some timing problem with crossfading. I usually use a dynamic playlist which is feeded from one smart-playlist.
Recently there seems to be a issue with crossfading.
The smartplaylist takes some seconds to calculate (when using append this).
The effect is:
at the end of the current track crossfading (2sec/xine) starts 
the next song is played (fading is fine)
then when it appends the next upcoming track to the end of the playlist the just started song is skipped and the next begins (crossfading fine here too;)
when i modify my smartplaylist to be faster or deactivate crossfading this problem doesn't occur.
This worked fine a few weeks ago, so maybe some check after track append or sth. leads to the skip? 

The term in the smart playlist that causes the most time and leads to the skip: album does not contain "somestring"
