gis:link-dataset and user-defined breed causes crash

[mrerrormessage]

From the ccl-gis mailing list

I think there is a bug in the GIS-extension: when using "gis:link-dataset" together with a link-set built from a user-defined "undirected-link-breed" with additional properties, the model crashes.
It's not a problem when either the links are not of a own breed or when they don't own additional properties, but in combination of both it doesn't work.

The error was as follows:

Extension exception: null

error while edge 0 1 running GIS:LINK-DATASET

  called by procedure TEST
