I believe that Portable GIMP leaves a .gtk-bookmarks file in the Documents and Settings\User folder.
You are here
GIMP: .gtk-bookmarks
As did Portable Gaim...
John, are you redirecting USERPROFILE with PortableGaim?
~nm35 {blog} {personal space}
Mind you, I don't have a userprofile directory.

Sorry to bring back an old topic, i was just browsing the net for an answer and it seems i've found it.
In %UserProfile% folder i have:
One folder named ".thumbnails" wich contains thumbnails of some of my resized images.
.fonts.cache-1
.gtk-bookmarks
These are left overs from portable GIMP. If someone could do something about it, it would be great.
Thanks for reading.
Me thinks you need to search a bit more. See here:

It's being fixed in 2.2.13 (already posted at the above link as a pre-release). I'm in the process of posting the final (same as PR3) now.
