Hi Nicolas,

I have seen this error once before from GEMS on Linux. It is really
hard to tell what is causing it since it comes from deep within the
Eclipse internals (on the native and not Java side). I do GEMS Linux
testing with Eclipse 3.2 on Fedora Core 3. What version of Draw2d/GEf
are you using? What version of Eclipse do you have? I would try
getting the latest versions of those and see if that fixes the
problem.

Another way to fix this problem is to remove the Prolog plugin from
GEMS. The Prolog module creates the borders that leads to this error.
To disable the prolog module, delete the folder:

org.gems.designer.dsml.kb

from you Eclipse plugins directory.

Thanks,

Jules
