I've got it. I did not compile the ethereal.exe executable, but only the
dissector. The ethereal.exe was version 0.10.0, the trunk is version 0.10.5.

After compiling most of the project I got it running. A feew changes in the
makefile give me the chance to debug through the ethereal code.

How is the dependency between Ethereal version and plugin version? Can this
be solved in a more flexible way?

It seems to be ok what you are doing, some other dissectors are doing it 
the same way.

I would think you have a bug somewhere at registering the stuff in your 
proto_register_... function, so Ethereal's internal data gets a bit 
confused.

You may try to reduce the stuff in your registering function to a 
minimum and see if the problem still remains.
