%%%Actually the import works but due to the huge model with 16000 individual objects it takes a very long time to run. I was able to find one reason for the long runtime (the scene was updated over and over again for each object).

I have committed a partial performance optimization in revision 54398. This speeds up the object creation by a factor of about 100 for this particular model. In that fix i also introduced some Blender Console logging messages, so you can see at least that something happens.

However when you test it now you will note that blender still takes a ~2 minutes before it starts the import and it takes an even longer time (10 minutes) to clean up before it returns to the scene. I still need to find the reason why that happens (I will keep the report open for that).%%%

%%%I can not do anything for speed optimizations right now (due to running out of time)
And since the primary problem is fixed (blender no longer hangs) i will close this report.

However i believe we should review the Importer to optimize it further.
This may be put back on the list for Blender 2.67%%%
