Won't save. "unknown error" Synced with Dropbox

[GoogleCodeExporter]

What steps will reproduce the problem?
1.  Open Keepnote
2.  Start typing/modifying.  Auto-saves all the while.
3.  After it has been open for a while you realize that it hasn't been saved.  
You try to force it to save but it gives you a pop up.  "unknown error."  Any 
attempt to open any other note gives you the same pop up.  One has to close 
keepnote and re-open it to restore functionality, but any recent changes will 
be lost.  

What is the expected output? What do you see instead?


What version of the product are you using? On what operating system?

Keepnote 0.7.8
Windows 7 Pro SP1.  


Please provide any additional information below.

Attached the error log.  

KeepNote works beautifully on Ubuntu, couldn't be happier.  My work laptop is 
windows and I switch between the two, hence the sync in Dropbox.
