Can't add trackers when creating torrents

[miskoala]

I use Deluge git master branch on Arch Linux
I try to add trackers when creating torrent in gtkui, click on 'add' button in tracker window and nothing happens, except i get error in console:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/deluge/ui/gtkui/createtorrentdialog.py", line 439, in _on_button_add_clicked
    dialog.set_transient_for(self.dialog)
AttributeError: 'NoneType' object has no attribute 'set_transient_for'
