I'm getting this error also, but in my case it is not connected to timestamp, but when there is a line with a bullet, but no text on it.
The bug can be reproduced by putting a "bullet" in the beginning of a line, syncing to Ubuntu One and after that trying to open with Tomdroid 0.4.1.

I attached a screenshot of the note.
