I removed default PLT. Regenerated it and got the same error.

BUT...you will not get this error, since you use official dialyzer which
has a bug - it does not recognize attribute "-behavior" only
"-behaviour". The bug has been discussed some time ago and the patch is
on its way. Just change "-behavior" to "-behaviour" and I'm sure you'll
get the error.

Sorry for this, I should have told you...
