[PLUG] Left over "artifact?" when doing screenshots, sometimes

[Dick Steffens]

Sometimes, when I do a screenshot, I get, in addition to the image I 
want, another "file" that ends in .part. While it shows up on Caja, but 
it doesn't show up in the terminal. Attempting to delete it gives me an 
error message telling me there is no such file or directory. It goes 
away if I reboot, but I don't know another way to get rid of it.

Any ideas?
