>Description:
Installing the noto-ttf package causes issues with the 8.0 X11R7 font handling. Specifically both X and fc-cache from /usr/X11R7 will hang indefinitely reading font data. fc-cache from pkgsrc is fine.

This could have been filed as pkg or xsrc, but assuming xsrc makes more sense as its an easy way to mess up an 8.x box
