Sometimes our internet connection outs or we're maxing it out with downloads. If DF happens to check for a wallpaper at that time then it complains that it can't find the user in a popup (in actual fact it can't make a call). This is pretty annoying, especially if you're working at the time (or in my case debugging so the alert throws you a little (or the sounds does at least)).

What I propose is two solutions (both would be nice):
1. Offer the option to disable the alert
2. If this is the case, look in the folder for any previous wallpapers and use those temporarily.

Just a thought.
