The problem seems to be caused by the combination of these
two lines in "nosryreaction.py" (extended template, version
0.4.1)

            change_note = cl.generateChangeNote(nodeid,
oldvalues)
            cl.sendmessage(nodeid, msgid, change_note)

The third argument to sendmessage() is supposed to be a
dict.  (it is frontend agnostic)  This appears to be fixed
in the CVS version.  I'll find out soon enough ...
