DockbarX Preference Dialog crashing on New Version

Distribution: Ubuntu 10.04.1 Lucid Lynx LTS
DockbarX Version: x.0.39.7 (latest)

     Hello, when I start DockbarX, it runs fine. However, when I go to configure it by right clicking its applet in the panel and selecting "Properties," there is no response. Under further investigation, I found out that by typing in "dbx_preference.py" in the terminal, it outputs the following error:

/usr/share/themes/NOX/gtk-2.0/gtkrc:233: Murrine configuration option "gradients" is no longer supported and will be ignored.
Traceback (most recent call last):
  File "/usr/bin/dbx_preference.py", line 1277, in <module>
    PrefDialog()
  File "/usr/bin/dbx_preference.py", line 714, in __init__
    self.update()
  File "/usr/bin/dbx_preference.py", line 906, in update
    }[self.globals.settings['workspace_behavior'].lower()]
KeyError: 'ingore'

     Odd thing is, I've searched "usr/bin/dbx_preference.py" for the text "ingore," which could be the typo causing the crash. Nothing results. Please help.
