Richard, the only problem with this is that it completely breaks usage of 
QByteArrays for PerlQt. Logan has some apps in PhoeNUX OS that actually use 
QByteArray constructs, thus the reason WHY he patched our build of 
kdebindings to get it working and submitted the patch to kde-devel. The 
definitive plan for PheoNUX is to have the Perl Qt3 / KDE bindings solidly 
working for all apps that we are developing, and then port the codebase of 
PerlQt/PerlKDE to Qt4 / KDE 4 so we get a sane path for when KDE 4 is out. 
This measn that short-changing the binding in this case isn't a good option 
unless we can get QByteArrays working with the marshaller.
