error when starting emacs

[Ike Swetlitz]

Hello,

I have a Dell Latitutet D600 on which I am running Ubuntu 10.04. I installed Emacs23 a few minutes ago using the command: "sudo apt-get emacs." Now, whenever I start emacs, these messages appear:

** (emacs:2295): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed


** (emacs:2295): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed


** (emacs:2295): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed


** (emacs:2295): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed


** (emacs:2295): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed


** (emacs:2295): CRITICAL **: murrine_style_draw_box: assertion `height >= -1' failed

Sometimes the numbers following "emacs" in the parenthesis are different. This doesn't seem to impact the functionality of emacs. Does anybody know what is going on here, and how I can prevent these errors, or if I should just ignore them?

Thanks,

Ike
