No, it is the same changes, but made on a 9.10 system's files and recreated as a patch. To build a version to test, you need to do something like this (assuming you have not got this far already):
sudo apt-get build-dep f-spot
apt-get source f-spot
./configure --prefix=/tmp/f-spot --disable-scrollkeeper
At this point you should have a working version of the unpatched F-spot in the temporary installation directory, and you can test it with:
Check it works, and has the usual problem. Then go back and fix it with:
patch -p1 < ../test.debdiff
(assuming you saved my patch in ~/f-spot-build) Then test the patched version again with this:
If it is all happy and you like it, then re-name the /usr/lib/f-spot/f-spot.exe file and copy your built version to that directory, then change it to be root owned, something like:
sudo mv f-spot.exe f-spot.exe.original
sudo cp /tmp/f-spot/bin/f-spot.exe .
sudo chown root:root f-spot.exe
Hopefully that will work (not tried last steps to install, on work PC which is 10.04 just now) Note that the /tmp/f-spot test location I used here will normally be deleted on reboot, so you might want to consider putting it elsewhere if you are planning on a lot of testing, etc. You can re-create the directory and re-populate it with 'make install' as needed though.
