Due to PyQt licensing, we are not permitted to release the ArtistView as source except to other commercial PyQt developers.
Fedora 17 is not officially supported by PipelineFX. There very well may a library conflict with the version you are using. Which RPM did you install?
You may want to try to open ArtistView with the '-d' option, as it will be more verbose during startup (assuming you get through bootstrapping).
If you have a support contract with PipelineFX, please open a ticket by mailing into support@pipelinefx.com so that we may assist you further.
