Thanks Phillip, thanks Yuki ! 

Apt-get does indeed say that the patch is applied. Being reassured, I
re-downloaded a fresh copy of the source, and tried to compile it
straight away, without any of my modifications... it worked !
So I replaced the 4 icons that I wanted to change, and tried again... it
failed again ! It was complaining about one of the 4 icons, I removed it
(put the original back in place ie), leaving the other 3 icons though,
and it compiled ! so it's quite straight-forward really, but I don't
have any idea why it is having problems with that other icon. It's the
one called "icon.xpm" in the /src/icon directory. I replaced it with the
icon "gqview.png", found at the root of the source directory. I used
Gimp to convert from png to xpm. Maybe there was a problem with the
conversion, no idea ! :o(
