sample manifest from akamai-progressive.irt.de

When playing one of the German DVB-T2 preview DASH streames stream I get an
error
>> gstmpdparser.c:1645:gst_mpdparser_parse_mult_seg_base_type_ext: segment has neither duration nor timeline 
The manifest contains SegmentTemplate nodes both in the AdaptationSet and in
the Representation nodes. The SegmentTemplate in AdaptationSet does not contain
a duration attribute and therefore the parser bails out (without examining the
sub-nodes).

Partiell manifest:
---
<AdaptationSet segmentAlignment="true" bitstreamSwitching="true"
maxWidth="1280" maxHeight="720" maxFrameRate="50" par="16:9" lang="und">
  <Role schemeIdUri="urn:mpeg:dash:role:2011" value="main"/>
  <SegmentTemplate initialization="V-1280x720p50_
libx264_high_yuv420p_gop100_bit3584k_term5-2-5-14-1_set1_init.mp4"/>
  <Representation id="164950" mimeType="video/mp4" codecs="avc1.640020"
