Well it only involved shortening a string by one character, and KHexEdit
makes is very easy, it was easier than setting up a whole build setup.

Thats a pitty.  Who builds the debs on the KDE site.  Currently they are built
in a different way to the Debian debs (different libraries, different 
options etc), it is a great shame that we can not get both built the same
way and then we would not have to have everything done twice!
