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.

    #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.
