Thanks for the example file. As you probably expected, it compiles fine
on my computer (although it was good to check). 

How did you install LyX? Did you install it from the Ubuntu repository,
or a PPA, or did you manually compile?

When you do the export, do you get an error dialog? What does the
message pane say right after doing the export?

The line about the assertion in your output means that LyX did not
detect an error when exporting but at the same time there is no export
file. So LyX is just as confused as we are it seems.

Best,

Scott
