don't know if it's really a bug, but it doesn't seem like a user configuration issue either. xfwm4 (CVS20040707) won't start with the error attached below. Seems that some entries in ${prefix}/share/xfwm4/defaults are missing? $ xfwm4 missing value for option fullscreen_key ** (xfwm4:16356): WARNING **: xfwm4: Missing values in defaults file ** (xfwm4:16356): WARNING **: xfwm4: Missing data from default files
the "defaults" file is built from defaults.in, but make fails to check dependency btween these files. from your source tree, do: xfwm4/defaults/defaults and redo the configure/make/make install
Err I mean rm xfwm4/defaults/defaults then redo the configure/make/make install
