Hi Konglom.
I have not done a bug report yet, but i will research deeper in it when i get the chance. Please observe that i'm not an expert in Linux, and the logout seems quite random up to this point, making me really confused about the true nature of the possible bug. I don't really have the time right now to sit and debug pure data, but i will do my best to help with the little resources i have. I am trying to make a full transition to Linux, everything about the OS is amazing, but i really cannot live without Pure Data, so i need to get this sorted out.
If i should come across a solution i will let you know. In the meantime, you could try PDL2ork... Haven't done it yet myself, which may be considered stupid, but i guess i am stupid. I'm gonna try it as soon as i can.
