Reproduce: In Xubuntu (xfce), go to Settings Manager -> Appearance -> Fonts -> Default Font, select an installed fixed-width, bitmapped .pcf font (e.g. ProFont). Desktop crashes; the new font does appear in the apport dialogs, but attempting to log back into the session, xfdesktop crashes with an assert in cairo, with gtk up the stacktrace:

cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion `!scaled_font->cache_frozen' failed.

To undo the change I had to remove the GTK Font property in xfce4's xsettings.xml config file.
