( 1 ) Open a terminal with ctrl + alt + t
( 2 ) Type sudo gedit /usr/bin/gdevilspie and press enter
( 3 ) Enter your password and press enter
( 4 ) If you do not see line numbers, click the edit menu in gedit, then click preferences ( look for the check box "show line numbers" and check it
( 5 ) Scroll down to line 374 and put a # symbol to the far left of the line ( prefix the line with # )
( 6 ) Press ctrl + s to save the changes and then exit out of gedit ( maybe give it a few seconds to finish saving before exiting though )
( 7 ) You are done with the fix, you can now launch gdevilspie and it ( should ) work.

you want run autostart you write only 'devilspie -a' on command line ;)
