xfce4-terminal had stolen 1G of memory

My xfce4-terminal had stolen 1G of memory and I
could not open a new terminal (xubuntu) until I closed them all
It just opens a new terminal window but no prompt found

I guess it is due all the crap coming out of the debug-logs
and then the buffers are full using up 1G
(I use the max value @scroll-back because I need it allot)

If I have @next failure some more time I will try to find out why this is happening

after I had a small of time, I figured out that with the option --disable-server
you can start a extra terminal without registering it into the DBUS session
then you can continue your work or just running out of memory
