xulrunner rendering issues ?

[Denis Leroy <denis poolshark org>]

On my rawhide setup, both epiphany and galeon are very much unusable at 
this point because of font and image sizes going haywire. Screenshot :

Left is epiphany. Top right is galeon (with zoom set at 100%). Bottom 
right is firefox, which looks good. A quick bugzilla search came up 
empty, so am I the only one affected ??
