Often an "MalformedBundleException" message results from Linux file (or
directory) permissions not allowing access to an activity's
activity.info file.  That is the case here - the Linux permissions on
Paint.activity/activity/activity.info are '-rw-------', which permits
access only by userid 500.  [Under Rainbow, when that Activity runs it
is under userid 1000-something.]  I changed the permissions on that file
to '-rw-r--r--', and Paint-28 ran as it should on a build-802 system.
