[Libreoffice] application/vnd.sun.xml.report.chart as chart media type

Hi there,

While investigating this

https://bugs.freedesktop.org/show_bug.cgi?id=36339

I've come to the realization that the bug doc contains chart objects
whose media type is application/vnd.sun.xml.report.chart.  But the media
type of normal chart object is normally
application/vnd.oasis.opendocument.chart.

Exploring deep into the code, all the evidence I've gathered points me
to the Sun report builder extension being associated with that media
type, but I'm not really an expert on how to use that extension.

Does anyone have any clue how a chart in a calc document could end up
with that report.chart media type instead of the regular
opendocument.chart one?

Thanks a bunch,

Kohei
