Hello!

A recent email discussion with Andre made me aware (again) of the 
incompatability between QPL and GPL. Not sure we have settled this issued, but 
I googled it and found the following link:

  http://www.gnu.org/licenses/license-list.html

scroll down to QPL. Here they suggest the following solution:

  However, if you have written a program that uses QPL-covered library 
  (called FOO), and you want to release your program under the GNU GPL, 
  you can easily do that. You can resolve the conflict for your program 
  by adding a notice like this to it:


     As a special exception, you have permission to link this 
     program with the FOO library and distribute executables, as 
     long as you follow the requirements of the GNU GPL in regard 
     to all of the software in the executable aside from FOO.

  You can do this, legally, if you are the copyright holder for the program.
  Add it in the source files, after the notice that says the program is
  covered by the GNU GPL.

For this to work all copyright holders need to agree. Not sure we need another 
author content process to use this solution though.
