Mixing points and linestrings does not work

I have a content type that have two sources of GEO information.
1: linestrings from a GPX formatet file.
2. Points from a image with GEO meta data (iPhone)
I tried to mix these data on the same map but that is not working as far as I can see.

If you define the return value to be “Points” you get the following error: “Wrong geometry type. Got POINT, was expecting linestring” on creating the node.

If you try to trick it by setting the image return value to be “linestring” you get no eroor but GOE is not able to decode WKT information from the image though the gpx-file is perfectly decoded.

So if you have return value setting on every but they still have to match the general setting? To me that does not make any sense.
