That might support my wild guess, that "Drop fontconfig tweaks" changings
could be related.

However, I don't get it, why recent dailies are not affected, while RC1 (and
alpha3) is ???
(That might be the reason, why this issue slipped through our attention until
now...)
Are there differences during build for the "release builds" (alpha, rc)
compared to the dailies?
CC'ing Steve for debian-cd side...
