There's one duplicated vertex which implies degraded face. It's currently known issue and it's being handled from Carve (boolean library we're using) side.
Workaround would be to run "Remove Doubles" operator.

Thanks for the report, but it actually duplicates issues which are already reported and assigned to me.

Thank you very much for analysing this problem. May it be possible as a
temporary work-around to replace the console message by some error dialog
which will avoid that Blender is completely stopping when this problem occur?
The risk to lose some recent not saved changes is very annoying.

It is only an idea. If it will be to much work, better spend the time to fix the real problem.
