Konqueror does not work with roundup.
You can display stuff, but submitting information does
not work.
This is most likely a konqueror bug. However as
Konqueror is established and roundup is not, people
will most likely perceive this as a roundup bug. (This
has happened to me a couple of times.)

Thus we should document this missbehaviour in detail, 
check for the bug id within the KDE bugtracking system,
open a new bug if necessary and follow the issue.
