Null pointer dereference in OGRCreateFromShapeBin

Description
Line 1289 does not have a catch all else to detect non-supported geometry.
This means that there is a potential to dereference a null pointer at line 1297.
This has happened to me with the sample ESRI FileGDB Shapes.gdb.

I'll double check the version we are using. It could be that we are using 1.9.0. If it is sorry for the duplicate report.

Replying to damiandixon:

I can confirm I'm currently using 1.9.0. Sorry for the miss-report.
Note:
See TracTickets
for help on using tickets.
Since GDAL 1.9.1 the code around line 1297 is the following :
if (*ppoGeom != NULL) (*ppoGeom)->setCoordinateDimension( bHasZ ? 3 : 2 );So I don't see where the null pointer dereference can occur. And I've tested with Shapes.gdb from the FileGDB SDK and didn't got crashes.
So I think it is a duplicate of #4441 that was fixed in r23752
Please re-open if I've missed something
