Hi Daniel,
Thanks for point this out.
The issue came up when Miro refactored some code so that the layout
mechanism
could store the layout parameters.
The issue here was that kepler/gui/src/org/kepler/gui/KeplerGraphFrame.java
has an _initBasicGraphFrame() method that has quite a bit of code
duplication.
As an initial workaround, I created 6 protected methods that include the
common code
and added a comment to BasicGraphFrame._initBasicGraphFrame so that
maybe we can
avoid this issue in the future.

I checked out a few previous revisions, and it appears r62155 is the
last revision that without the error.
