The program 'gnome-power-manager' received an X Window System error. This probably reflects a bug in the program. The error was 'BadAtom (invalid Atom parameter)'. (Details: serial 171 error_code 5 request_code 148 minor_code 15) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.)

Your backtrace is meanlingless. You need to install the debuginfo packages.

This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle. Changing version to '14'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Created attachment 438783 [details] output of 'bt full' Reproducible here (New 13" Macbook Pro [7,1]). Backtrace goes through gpm_brightness_output_get_internal in about the same way.

Created attachment 438871 [details] gnome-power-manager-2.31.6-backlight-is-None.patch The problem (at least for my machine) is that some part of the system (upower? kernel? who knows) doesn't know how to deal with the backlight brightness. So gpm_backlight_init does: backlight->priv->brightness = gpm_brightness_new (); which sets backlight->priv->brightness to 0 (i.e. None). So when we get to gpm_backlight_brightness_evaluate_and_set(), we end up trying to read the X property for something that's None, and X barfs at us, and gpm crashes. Okay. So. Adding a nice simple check to gpm_brightness_output_get_internal(): if (brightness->priv->backlight == None) return FALSE; lets gpm at least start up and run without crashing. Brightness control obviously isn't working, and it doesn't think I have a lid on my laptop, but at least we're not crashing.
