Hmm. That is supposed to work. If any user of the NautilusFile in
nautilus has expressed an interest in the extension info for the file
then if you invalidate it it should be re-read by nautilus.

Strange. Just calling the invalidate_extension_info in a timeout should
work. Might be a bug of some sort.

In recent version (2.16 i think) there is support for this.
