Oh, man. Sorry you ran into this. This has been fixed internally.
So, as you mentioned, for this Tech Preview users can work around this by installing the libart_lgpl-2 library as included with the libart_lgpl package:
> SUSE: zypper in libart_lgpl_2-2
> Debian/Ubuntu: apt-get install libart-2.0-2
> RedHat/Fedora: Whatever method to install libart_lgpl-2*
Thanks much for posting -- hopefully anyone else seeing the same will find this post quickly.
