Problem with lyrics

[Lorenzo Bicci]

Hi everybody!
Here's the problem: when compiling the file below, no syllable gets assigned to 
the first note of the 5th bar of the second voice (see the PDF here: 
http://www.ntontopupu.com/prova.pdf). I tried with both versions 2.10 (on 
Linux) and 2.12 (on
Windows). Did i make any error in the .ly file or is this a bug? In case this 
is a bug, anyone can suggest me a workaround?
Thanks,

Lorenzo
