Bug#526057: po2xml: endless loop on empty para tag

[Frans Pop <elendil@planet.nl>]

Package: poxml
Version: 4:4.2.2-1
Severity: important
Forwarded: http://bugs.kde.org/show_bug.cgi?id=190974

If the source XML file contains an empty <para> tag, po2xml from KDE 4.2.2 
will end up in an endless loop: the warning "found empty tag para" is 
printed endlessly.

This is a regression as the version from KDE 3.5 handled that situation
correctly: it would print the warning once and continue to generate a 
correct translated XML file.

Setting severity important as this breaks builds of Debian's Installation 
Guide. Test case available in upstream BR.
