#377 new defect

MultiGeometries can't be read from MapInfo .tab file

Description

When reading from a MapInfo .tab file using the OGR provider, the geometries are all returned as MultiGeometry but all of them are apparently empty (GetCount() returns 0 and GetText() returns "GEOMETRYCOLLECTION()"). Using the ogrinfo command line utility from GDAL 1.4.2 and 1.4.4 shows valid geometry data for each record in the same file, so there may be a bug somewhere (in the OGR provider, the WKB to FGF conversion code or the 1.4.3 version of GDAL distributed with FDO).

I will attach the layer this problem is occurring with along with an abridged source file to this ticket.

I think the culprit here is missing handling code for multigeometries in the Fgf2Wkb and Wkb2Fgf functions in OgrFdoUtil.cpp.
