Next to I have seen, this bug occures when you change the emacs' window's size. Everytime you change the size of the windows, the message appears in the terminal. Moreover, i've put "scroll-bar" on "None" value and noticed that the message stoped to appear as soon as the scrool bar is off.
Moreover, on my side, this bug occures only when i'm under "Ambiance" or "Radiance" theme. I hope it will help you to solve it and have to apologize for my bad english ^ ^ See you :) -- warning spam on stdout: CRITICAL **: murrine_style_draw_box_gap: assertion `height >= -1' failed https://bugs.launchpad.net/bugs/538499 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
