Comment 5 for bug 711192

I got the same error on Ubuntu 11.10 with Tomboy version 1.8.0, a dialog said that note sync failed but the "details" box was empty. Quitting tomboy and starting it from command line, after trying to sync notes I saw:

[ERROR 15:10:43.880] Synchronization failed with the following exception: A note with this title already exists: Oggi: mercoledì 22 agosto 2012

(Tomboy:11544): GLib-CRITICAL **: g_source_remove: assertion `tag > 0' failed

So deleting the named note (after copying its content somewhere else) solved the problem, but this messag should be in the dialog box.
