New description:

 r34679 x86gcc2hybrid. My previous installation was r34464. This KDL has
 cropped several times since installing this revision. I don't know an
 exact step to reproduce it at will. It is not limited to a particular
 application.

 Are there any other KDL commands that can be used? I'm willing to run a
 build with tracing or other debugging as well.
