Description of problem:
When using Autokey-GTK to stick a large bunch of text into the clipboard, I encounter the following error:

2015-06-08 10:00:05,418 DEBUG - iomediator - Send via clipboard
2015-06-08 10:00:05,418 DEBUG - interface - Sending string: u'To join via Browser:\n [...]'
2015-06-08 10:00:05,419 ERROR - interface - Error in X event loop thread
Traceback (most recent call last):

    self.clipBoard.set_text(string.encode("utf-8"))
TypeError: Gtk.Clipboard.set_text() takes exactly 3 arguments (2 given)

Autokey-gtk generally hangs for a minute or two, and eventually just gives up. 

Version-Release number of selected component (if applicable):
$ rpm -q autokey-gtk
autokey-gtk-0.90.4-6.fc21.noarch

How reproducible:


Steps to Reproduce:
1. Create new phrase that pastes using cardboard. Maybe with multiple lines.
2. Try to use the new phrase.

Actual results:
Autokey-gtk seems to hang for a time, and running debug shows the following error:
TypeError: Gtk.Clipboard.set_text() takes exactly 3 arguments (2 given)

Expected results:
Pastes text.

Additional info:
I replaced line 537 of autokey/interface.py with the following:
            self.clipBoard.set_text(string.encode("utf-8"), len=-1)

It seems to work fine now. It would be great if this could be fixed through a patch to the Feodra RPM, considering there's not been movement on the upstream issue for years.

Existing, stale issue.
