[redland] SegFault with python interface

[Dave Beckett]

Just to report to the list - the segfault was caused by the test
python program trying to create a berekely DB based storage when that
module wasn't compiled into Redland.  The demo program failed to
detect this by passing back a None to python.  The quick fix is to
remove the 'bdb' from python/test/test.py line 26 and replace with
'memory' - which I will fix for the next release
