DateTime::Format::ICal bug : DTSTART value in recurrences not converted to DateTime

Hi,

I have a problem with this expression (Second wednesday of every month, at
20:00) that I'm using with DateTime::Format::ICal->parse_recurrence() :
FREQ=MONTHLY;BYDAY=2WE;DTSTART=20090201T200000Z;COUNT=12

Here is the test case:
perl -MDateTime::Format::ICal -e
"DateTime::Format::ICal->parse_recurrence(recurrence=>'FREQ=MONTHLY;BYDAY=2WE;DTSTART=20090201T200000Z;COUNT=12')"
The 'start' parameter ("20090201t200000z") to DateTime::Span::from_datetimes
was a 'scalar', which is not one of the allowed types: object
 at C:/strawberry/perl/site/lib/DateTime/Span.pm line 37
    DateTime::Span::from_datetimes(undef, 'start', '20090201t200000z')

    DateTime::Event::ICal::recur('DateTime::Event::ICal', 'freq', 'monthly',

Settings/omengue/Documents/Eclipse/Test POE Scheduler/test-ical-recur.pl

It looks like a conversion of the string value of dtstart to a DateTime
object is missing...
