Sorry about posting here. Couldn't find a bug report link on your website:

wheezy/sid (Really Mint Linux but whatever)

openjdk-7-jre:i386

$ sudo dpkg -i reader-1.1.1.deb

dpkg: error processing reader-1.1.1.deb (--install):

parsing file '/var/lib/dpkg/tmp.ci/control' near line 2 package 'reader':

Errors were encountered while processing: reader-1.1.1.deb

Hope that helps.
