Comment (by nicos@…):

 The problem has been symptomatically identified, and reported upstream.
 There is not necessarily the resources in Macports to fix issues directly
 in the code when upstream does not follow up. I myself do not know the
 code of okular well enough to identify where this could be tackled.

 However, if you happen to have a patch fixing the issue to propose, it
 would be fully considered.
