The abrt-applet package still installs a binary called cc-applet. And the cc-applet tries to run /usr/bin/cc-gui which doesn't exist anymore because it has been renamed to abrt-gui Furthermore, the -applet package ought to require the -gui package if it tries to run a binary from that package, or they could just both live in the same package.
Fixed in git.
