Description of problem: Not sure how it happened, but the symptom was that I could no longer start many applications. I had about 30 of these errors in ABRT.

We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs. Fedora 28 has now been rebased to 4.18.10-300.fc28. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29. If you experience different issues, please open a new bug report for those.
I only saw this issue once (on August 22).
Probably some long lost corruption. I think it makes sense to close for now.
