Running "skencil" from the terminal $:
 
$ skencil
Traceback (most recent call last):
  File "/usr/bin/skencil-2.7", line 6, in <module>

    font_size = int(vals[-1])
IndexError: list index out of range
 
----------
 
It fails on gtkutils.py because the font, that is passed to vals[] that is empty, is got around line 42 in this way:
 
<---
import os
from tempfile import NamedTemporaryFile
 
command = "import gtk;w = gtk.Window();w.realize();style=w.get_style(); print style.font_desc.to_string();"
os.system('python -c "%s" >%s 2>/dev/null' % (command, tmpfile.name))
 
font = tmpfile.readline().strip()
--->
 
The 'command' just fails in python3 (system's default), but it works on python2.7, because of pygtk:
 
# emerge -pv pygtk

Thus, the workaround was just change 'python' to 'python2.7' on line 43 of gtkutils.py
   os.system('python2.7 -c "%s" >%s 2>/dev/null' % (command, tmpfile.name))
 
In the same way, another error occurs because of line 225 of the same file:
os.system('python -c "%s" >%s 2>/dev/null' % (command, tmpfile.name))
 
which also is corrected by just changing to 'python2.7'
os.system('python2.7 -c "%s" >%s 2>/dev/null' % (command, tmpfile.name))

CCing treecleaners (dead since 2010 and needs migration to new python eclasses)
