Hi! I got the same problem (Lucid 32-bit - fresh install, acer notebook, Ambiance theme, Emacs GTK). Such messages appears when I move the mouse around the left part of the Minibuffer (on the up/down arrows), or when I redimension the window.
There may be no link, but we never know (that's why I mention it)... it is sometimes (but not always!) impossible to redimension a window from its middle left/right border. Does that mean there's a problem in the way Ambiance defines windows??? -- 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
