This is because you did not (yet) follow my urge to load the default
preferences for the CPDs.

Do you really know what you entered here? None of the default cpfind
related CPD entries resemble what you used.

If you really are that reluctant to loose your old settings, you can
preserve them for later reference:
o Close all Hugin apps
o Open a terminal window on your home directory
o Issue "mv .hugin .hugin.old"
o Restart hugin
o Re-create your project in Hugin

The .hugin settings file is a normal text file you can open with any
decent text editor (but you never should attempt to do changes using a
text editor there). But you can easily spot the differences between the
old and the new version and, if you really must, can copy back the
.hugin.old to .hugin to get back to your old (non-working) settings.

BTW, I got 12 CPs from the two images you attached to this bug report
using the default Hugin's cpfind and, after optimization, I got a
solution with
average control point distance: 1.012091
 standard deviation: 0.738920
 maximum: 2.263629
Nice pics, BTW.

The problem are your outdated settings, not Hugin. And removing Hugin
will *not* remove these settings. You either have to reload them from
defaults, or, much easier, delete the .hugin file in your home
directory. Hugin will recreate this file using the new defaults upon the
next start up of Hugin.
