      When I try to paste local clipboard content to a text editor in the remote machine by pressing Ctrl+V keyboard shortcut, the text editor "Open File" dialog pops up.

      Steps to reproduce

      1. Copy the following text to the local clipboard
         #copied from local clipboard#
      1. Connect to a remote machine using Guacamole
      2. Open a text editor (e.g. gedit, notepad) in the remote machine
      3. Press Ctrl+V

      Expected behavior
      Local clipboard content is pasted to the text editor in the remote machine.

      Actual behavior
      "Open File" dialog pops up in the remote machine.
