When you run the gnome-terminal while using the Sawmill wm, gnome-terminal exits with this error: Gdk-ERROR **: BadDrawable (Invalid Pixmap or Window parameter) serial 516 error_code 9 request_code 14 minor_code 0
I'm running sawmill and plenty of gnome-terminals, and I don't see this problem. Are you doing anything else out of the ordinary? Does it crash every time you try and run it? If not, how do you trigger the crash?
Strangely enough, it doesn't happen anymore. The only thing I've done since I tried it last is install a new kernel (compiled from source) and rebooted. I haven't done anything with neither GNOME nor Sawmill. But when it happened it happened every time and without me doing anything else than start the gnome-terminal program.
The problem is most likely that a background pixmap property was set by enlightenment; this stale property confused the gnome-terminal transparent-background code causing the crash. Rebooting fixed the problem since enlightenment was no longer there to set the background. Working on a patch now.
Should be fixed in gnome-libs-1.0.55-10
