Synchronization causes tomboy to crash due to temp file not being found.

[JasonH]

Primary cause of the error seems to be:
[ERROR 09:46:31.795] Exception while saving note: System.IO.FileNotFoundException: /home/jherr/.local/share/tomboy/f8670d08-de0d-468e-bd6a-720ef6998ee8.note.tmp does not exist

Full debug log will be at end of bug report.

Was synchronizing notes from home to work and work to home when I caused this. Was not paying attention to order so I cannot provide much help, just that I wrote a file on one machine, synced, looked at it on the other, synced, closed windows (or rather they crashed). Since then, every sync has caused my (second machine) laptop's run of tomboy to crash. Looks to be trying to reconcile the two touched files with close timestamps and has failed?

Wish I could give more data on that issue as it it the interesting part.

The boring part. I worked around this by reading the logs (using the --debug option and running from the commandline) deleting the offending note and getting on with life. If there is a way to handle this missing tmp note file or putting some defensive coding around handling this file being missing, I'd lurve it. (If I get free time, I'll try to look at it myself).

You might wish to split this into two issues. Tight synchronization to Ubuntu One with possible time issues and the defense against the temp file missing.
