Unfortunately to get an answer you'll probably have to post to the Xfce Mailing List, you can find the ML info here.

on a redhat 5.3 distribution I'm trying to build xfce 4.6.1 on an isolate installation prefix. I think I have installed in this same prefix all required dependencies. After installation and after adding xfce to my gdm configuration I can successfully login into the xfce desktop (xfwm up and running.) However, when I execute xfwm4-settings it cores dump as shown in the back trace included below (some variable values also included.)

For some reason, at xfwm4-settings.c:480 a call to xfconf_channel_get_property returns a 'value' which passed to xfwm_settings_title_alignment_property_changed makes the program to crash.

Could this be just a misconfiguration somewhere in my ~/.config files or perhaps a bigger show stopper to my attempt to build on top of RH5.3?

many thanks,
Rodrigo
