[Therion] Infinite loop in therion 5.3.9

Hi, I have an infinite loop with Therion 5.3.9 on Ubuntu. I have to kill the processus to stop it. When I look to the Therion tmp working directory, there is a big file (some Go if I don't stop fastly) witch name is : th_pagedef.tex The begining of this file is in attachment. The infinite loop repeat this ending line : \PL{q}\PL{1.00 0.03 -0.03 1.00 -nan -inf cm}\PB{0}{0}{\THWgrida}\PL{Q}% I don't understand tex language... In attachment, the zip file with the file I compile. Sorry for my english, Bertrand
