You’re right that the doc-string is misleading.  @var{thickness} is required as 
an argument but if its value is not a number then an appropriate value is 
selected based on @var{style}.  If the user hasn’t explicitly specified a 
number for the thickness of the whiteout, then this procedure is called with an 
empty/null/non-number value for @var{thickness}.

I don’t think it would have prevented this error but it probably makes sense to 
make it an optional argument.  I’ll prepare a patch for that so the code will 
match the doc string.
