This probably can considered as a bug, but I see it as a widely used behaviour 
pattern, used to avoid data loss in the most critical phase of program execution 
of writing modified content.
When I write utilities for my own usage, I do often resort to this solution. 
When the program fails or is killed in the moment of writing, the old file is 
left intact and the residues of the incompletely written new file can be 
discarded later. So I would not see this as a bug but as a valuable feature, 
especially when dealing with image files of which many of the users don't make 
backups first.

just checked the gimp: it indeed writes the file directly. So there definitely 
is confusion ahead.
