It would hurt a lot *not* installing the patch. The bigger problem is that the
other distributions including windows, Mac OS X, BSD, ... server must now
install the blacklist too. I guess non debian systems now have bigger problems
than debian.

Yes. 1019

And then pango gave:
(testproject:27449): Pango-WARNING **: error opening config file
'/etc/pango/pangorc': Too many open files
Apparently CreateGUID is buggy and should not be used under Linux.
