Hello, i use 0.2.4 version and have this error when trying to start gtg from terminal:

[korg@archlinux ~]$ gtg
  File "/usr/bin/gtg", line 47
    print "Could not open X display"
                                   ^
SyntaxError: invalid syntax
[korg@archlinux ~]$

Are you unde X? Are you able to launch anything else from this terminal? (try xeyes)
