Look at the diff for this changeset:

http://hg.savannah.gnu.org/hgweb/octave/rev/6c0fce0632a4

and where there is ->setFocus, put into place some value from the table 
listed here:

http://qt-project.org/doc/qt-4.8/qwidget.html#setFocus
http://qt-project.org/doc/qt-4.8/qt.html#FocusReason-enum

See what happens and whether you can make any sense of things.  Notice 
that an "8" (your result), is not a valid entry in the table. 
setFocus() is an overloaded variant, so I don't know what the issue is. 
 Maybe that's a bug in Qt on the system you are using.
