I doubt you really mean "recently".  Anyway, that was not a mistake.  That
line will cause lots of problems with clock skews and changes (which are not
uncommon at new installations).  Instead, the cache stores the dir timestamp,
and the two are compared for equality.

I think the approach Diego proposes may be real the fix.  However, I'm puzzled
as live font installation and uninstallation both work for me correctly.  I'll
check it out again.

Diego, which fontconfig version are you using?

Makes me wonder, what patches do you carry around in Novell that should be
upstream?  Please file them in bugzilla and I'll take a look.  We're getting
2.7 out really soon.
