I have noticed several times since upgrading to Fedora 11, gpk-application 2.27.2, that after installing a GUI application, the PackageKit run program dialog comes up and shows no program/package names next to the icons for the program(s) you can run. Dialog functions correctly otherwise.
This probably has affected ~30% of the GUI applications I have installed.
We moved the upstream bugtracker to GitHub a long time ago. If this issue still affects you please re-create the issue here: https://github.com/hughsie/PackageKit/issues
Sorry for the impersonal message, and fingers crossed your issue no longer happens. Thanks.
