This bug appears to have been reported against 'rawhide' during the Fedora 23 development cycle.
Changing version to '23'.

(As we did not run this process for some time, it could affect also pre-Fedora 23 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 23 End Of Life. Thank you.)

I will try as and when I can over the weekend and let you know asap.

Data dumps for crashed cinnamon-screensaver-2.6.4-3.fc23

The answer is no, the problem is still present unfortunately. Also the backtrace was unusable so reporting disabled. I've compressed the files so hopefully you can still find something of use.

Mike,
I noticed that creating a backtrace fails because of missing debuginfo files.
1) go to /var/spool/abrt/<your-bug>
2) check the files component and cmdline if you are in right directory
3) run 'abrt-action-analyze-ccpp-local'
4) check backtrace for missing debuginfo files
ie.
0x410e7d30  0x410f05e3  Yes (*)     /lib/libudev.so.1
(*): Shared library is missing debugging information.
But ignore /lib/libudev.so.1, this is always marked for some reasons, and part of systemd :)
5) install the missing debuginfos files
6) run abrt-action-analyze-ccpp-local again

from file backtrace file

warning: the debug information found in "/var/cache/abrt-di/usr/lib/debug//usr/bin/cinnamon-screensaver.debug" does not match "/usr/bin/cinnamon-screensaver" (CRC mismatch).

Means cinnamon-screensaver and cinnamon-screensaver-debuginfo doesn't have the same version.
Update cinnamon-screensaver-debuginfo to right version and run 'abrt-action-analyze-ccpp-local' again please, than backtrace file should looks better.
Please attach only the file backtrace, that's enough.
Looks like dnf don't update debuginfo files.

Backtrace using cinnamon-screensaver-debuginfo-2.6.4-3.fc23.x86_64

It's still producing the same output after updating

Ok, the backtrace is really unusable.
But in general this is the way to create a usable backtrace.
It really help us to take a look first in the backtrace itself if debuginfo packages are missing before sending with abrt.
I noticed for myself in several abrt alarms that 'dnf' has a prob to find the debuginfo packages.

PS: delete the folder and wait for a new abrt alarm, maybe we have more luck than.

I can't get this to reproduce any longer. So hopefully it is fixed after all. It only happened once after updating the screensaver rpms and restarting.

I've been trying to trigger it with various different applications running while leaving the machine to go idle and activate the screensaver after 5 mins.
