MozPlugger 1.7.2 has been released. "It adds support for Acrobat Reader 7 and Evince, and fixes the bug that obscured parts of embedded windows when increasing the size of the browser." Bumping the 1.7.1 ebuild works fine on my x86 box.
Version 1.7.3 is now the latest release. BR, /ediap
Added to portage, thanks
