Don't think 7.0 standard is the problem. That's what I run and the gui loads fine.
There are a couple of presumably minor errors shown when running from the command line which do not seem to cause problems, as follows:

/usr/share/themes/MurrinaBlue/gtk-2.0/gtkrc:83: Murrine configuration option "scrollbar_color" is no longer supported and will be ignored.
/usr/share/themes/MurrinaBlue/gtk-2.0/gtkrc:83: Murrine configuration option "hilight_ratio" will be deprecated in future releases. Please use "highlight_shade" instead.
