Comment 0 for bug 492100

This is an error in syncdaemon, not nautilus-ubuntuone.

If the patch fixing #491777 is applied then the user is greeted with the following message:

Error creating share.
There was an error sharing the folder '$folder':
callback() takes exactly 2 arguments (1 given)

syncdaemon.log contains the following.
