[Inkscape-devel] CIip Path ID collision

I've got two different graphs, created in matlab and exported to svg using plot2svg[1]. When I try to import both of them into a single document, some sets of points in the second graphic don't show up. I've tracked the problem down to a clip path id collision. Both files define clip paths with the same ids, so when the second file is imported, its clip path url's point to clip paths from the first file.

Is there any kind of workaround for this sort of thing? Is this a bug? Shouldn't inkscape check IDs to make sure there aren't any collisions when importing files?
