Just a shot in the dark...

[rocketmouse at archlinux ~]$ grep theme .config/xfce4/xfconf/xfce-perchannel-xml/*
.config/xfce4/xfconf/xfce-perchannel-xml/xfwm4.xml:    <property name="theme" type="string" value="Default"/>

...perhaps replacing "Default" by a theme name works around the issue.
OTOH I don't know for what theme this value is used.

Ensure that the value...

[rocketmouse at archlinux ~]$ grep -i zen .config/xfce4/xfconf/xfce-perchannel-xml/*
.config/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml:    <property name="ThemeName" type="string" value="Zen-verda"/>

...is set to the wanted theme name and restart the window manager. I
don't know if     xfwm4 --replace     does replace itself, IOW does
cause a restart.

I never used it, but there's an app named xfce-theme-manager available,
but perhaps it doesn't set the theme, maybe it's just a theme editor or
what ever else.
