Blank screen at admin/build/themes with color module enabled.

I encountered this on a new linux and php5 installation of drupal 6.5 yesterday - I was intending to experiment with some D6 theming and so had installed a number of additional themes, but on attempting to access admin/build/themes all I found was a blank, white screen (and no html in firebug either).

My logs are as follows:

As you can see, at first I thought it was the additional themes which were causing the errors so I started removing them, but slightly different errors were instead caused by the next theme in the list.

On a hunch, I disabled the color module and this seemed to solve it - I can now access the theme selection pages. This isn't really ideal, as I'd quite like to use this component, so I thought I'd let you know about it as at least one other person has had this problem.

Thanks.
