Bug 1268289

Description of problem:
After update to version 0.98, fundamental keybindings such as CTRL+SHIFT+O/E/C/V (i.e. split horiz/vert, copy, paste) are not working.

Version-Release number of selected component (if applicable):
Name        : terminator
Arch        : noarch
Epoch       : 0
Version     : 0.98
Release     : 1.fc22

How reproducible:
Run terminator (either from another terminal emulator or from GNOME), press e.g. CTRL+SHIFT+O

Actual results:
^O appears in the terminal, and no action is executed.

Expected results:
Action corresponding to the keybinding should be executed, without outputs in the terminal.

Additional info:
Find below the debug output when running terminator with the -d option and pressing CTRL+SHIFT+O/E/C/V . Terminator seems to recognize the corresponding action, but nothing happens.

Downgrade to previous version of terminator solves the issue:
Name        : terminator
Arch        : noarch
Epoch       : 0
Version     : 0.97
Release     : 6.fc21
