[kepler-dev] Kepler - bug related to user.home settings

[Matt Jones]

Michal,

This change looks fairly innocuous and seems to be a reasonable change.
Thanks.  Please let us know how your testing against trunk goes, and if it
goes well, it seems reasonable to commit it so that it can be part of the
Kepler 2.4 release.
