Please describe the problem:
Please see http://www.botmanfamily.net/~aurelien/tmp/gimp-error.png

Under the windows XP version:

the "save as" dialog cannot generate previews (error about invalid encoding
appears, see image);
the same error dialog appears upon subsequent attempts to save the file. As far
as I can tell the file is saved OK but the dialog pops up so often (each time
anything happens which requires the preview in the icon/title bar to be updated)
that it gets so annoying that I cannot work on the file at all.


Steps to reproduce:
1. Create new image.
2. Choose "save as".
3. Click on "browse for other folders".
4. Whatever happens from now you get the error each time any preview needs to be
drawn, be it in save-as dialog or in title bar of window.


Actual results:
See image.

Expected results:
Not to see error dialog.

Does this happen every time?
Yes.
