Comment 16 for bug 370093

Ok, followed http://blog.ixti.ru/archives/6 (via https://bugs.launchpad.net/ubuntu/+source/gnash/+bug/422745 ) - and basically a line
   update-alternatives --remove-all xulrunner
in /var/lib/dpkg/info/xulrunner.prerm needs to be commented - however, just commenting it will cause the bash script to fail, so just replace that line with something like "echo blabla" and then it will be possible to sudo apt-get remove --purge xulrunner ...
