Couldn´t create new queue´s


I have the problem that everything works fine, but i have
problems to create a new queue. My first idea was that it is
a browser problem, but now I know it just works sometime. Most
of the time when I try to create the new queue I get the following
System error

while serving /Admin/Queues/Modify.html
error while executing /Admin/Queues/Modify.html [standard]:
Bizarre copy of CODE in aassign at /usr/lib/perl5/5.6.0/Carp/
line 79, line 47.

backtrace: /Admin/Queues/Modify.html [standard] <= /autohandler

Any idea???
