Description of problem:

GIMP doesn't handle spaces in files correctly. When I open an image, that has
spaces in its filename and then resave it, GIMP will replace it with %20. The
file ends up with %20 in its filename on disk. So, before it is written to disk
the %20 is not translated to a space.

Version-Release number of selected component (if applicable):
gimp-2.2.12-1.fc5

How reproducible:

Always

Steps to Reproduce:
1. open an image, save it to a file with spaces in its name
2. reopen the image, save it again. All spaces in the name will be replaced by %20
  
Actual results:

filename changed, spaces were replaced by %20

Expected results:

I would have expected that the spaces would be left intact.
