Problem fixed with PmWiki version 2.2.37! Thanks to Petko. In the end it 
was a non-functional iconv() implementation that returns an empty string 
under Solaris. Our data center had no bugfixes for this but Petko 
implementet further checks so a existing but wrong implemented library 
causes not the error with the Site.EditForm error message. Thanks!
