Description of problem: sfxr (the sound effects generator) upon launch either blips and exits or sits there with a black window and nothing happening


Version-Release number of selected component (if applicable):
sfxr.x86_64                                 1.2.1-6.fc28                @fedora 


How reproducible: Try to launch sfxr within the XFCE desktop environment.


Steps to Reproduce:
1. Launch sfxr either from the Application Finder utility or from an established launcher icon, or from command line.
2. Observe quick blip on screen and no sfxr running
3. If launched from command line, observe: Segmentation fault (core dumped)

=================
<submitter speculation>
It appears that sfxr is dependent on some obsolete packages (e.g. RPM-GPG-KEY-rpmfusion-free-fedora-22-primary), and that might be an avenue of root cause analysis. I would be happy to provide (after sanitizing personal info) the core dump file mentioned in the journal output if I knew where it was. That ABRT crashes might also be a useful indicator.
