[Pcmanfm-develop] crash when moving icons

[Jeremy C. R. <re...@re...>]

I was moving icons around -- I moved one and couldn't figure out how to 
get it lined up again. No matter what I tried I couldn't get it lined 
up. If I tried to move just a little (the icon was a directory) it 
assumed I was trying to move the directory into itself so a window 
popped up stating I can't do that.

Then I tried moving some more icons and pcmanfm desktop crashed:
