GTK2 UI errors

[micrococo]

Hi.

When running LX-Control-Center using the GTK2 user interface, there are some errors:

$ lx-control-center -u GTK2 
WARNING:root:Utils.__get_path : Can't find an existing file for relative path  None
ERROR:root:Utils.load_object(ini): error, when loading None as a ini file
/usr/lib64/python2.7/site-packages/gi/overrides/Gtk.py:50: RuntimeWarning: You  have imported the Gtk 2.0 module.  Because Gtk 2.0 was not designed for use with  introspection some of the interfaces and API will fail.  As such this is not  supported by the pygobject development team and we encourage you to port your  app to Gtk 3 or greater. PyGTK is the recomended python module to use with Gtk  2.0   
  warnings.warn(warn_msg, RuntimeWarning) 
WARNING:root:Utils.__get_path : Can't find an existing file for relative path  None

ERROR:root:Utils.load_object(ini): error, when loading None as a ini file

These error don't prevent the application from starting. But when you click Preferences there is an error and the Preferences widget shows nothing:

Traceback (most recent call last):

I didn't report this before because I wasn't sure whether you had finished issue #2 or not.

Greetings.

Thank you for the report, and sorry for the unstability, I'm still trying to make the code easier to maintain. I'll check this as soon as I can.

Oh, no, don't worry. I understand that the program is under development and bugs are unavoidable. Thanks to you for taking the time to develop the application and fix the bugs. There is no hurry at all :)
