That's great, thanks (also to David Gowers for his response too).

I'm still a relative novice with GTK- I learned what little I know in order to 
write this filter's dialog box- but I'll be taking a look at that.

In the meantime, I've uploaded the linear unsharp mask filter code (first 
version) and some example images here:-
http://home.freeuk.com/misacham/temp/mask.htm

(Note (a) the images are fairly large and (b) Yes, I know the filter code is 
slow and could probably be *much* faster; one thing at a time).

Like I said, I'd be very surprised if I was the first to think of this, but I 
wanted to play around with the idea on my own anyway. It's hardly a miracle 
cure for motion blur, but the results were pretty good; it certainly beats 
two-dimensional USM for that purpose.

[Gimp-developer] help - no more able to compile from cvs

[Marco Ciampa]

I've recently upgraded from ubuntu dapper to edgy and I'm no more able to
compile gimp from cvs. The error seems related to the pygimp section. Here
is the make log:

 Any hint?

It is due to a bug in pygtk which has since been fixed. See bug #381389 in 
Gnome bugzilla (http://bugzilla.gnome.org/show_bug.cgi?id=381389).
