Here is the deal:

QT2 licence fits the Debian Free Software Guidelines, so it can be included in
Debian.

But, it is more restrictive than the GPL, so it can not be linked against GPL
code, that means it can not be linked against KDE, dpkg or the Debian boot 
floppies. 

It is not really a case of Debian endorsing the QT2 licence, more a case of
reading the GPL and QT licences.

This is the important section from the GPL:
#   6. Each time you redistribute the Program (or any work based on the
# Program), the recipient automatically receives a license from the
# original licensor to copy, distribute or modify the Program subject to
# these terms and conditions.  You may not impose any further
# restrictions on the recipients' exercise of the rights granted herein.
# You are not responsible for enforcing compliance by third parties to
# this License.

There is one way out of this hole, call Qt a major component of the operating
system. The GPL has a clause that says it can be used with libraries
distributed under a more restrictive licence than the GPL, if that library is
normally distributed as a major component of the operating system. You could
argue if the system is based on KDE then Qt fits this description, but others
would disagree.
