This bug has been created based on an anonymous crash report requested by the package maintainer.
Report URL: http://faf.lab.eng.brq.redhat.com/faf/reports/bthash/aec7fda001a8f493cc29dd8b7bd0bf5e5076da3b/
The attached FAF report has no detailed backtrace.
I don't think we will be able to solve this without further data.
As highlighted by Thomas, the FAF report is missing detailed backtrace.
Closing this for insufficient data (seems anyway this failure is not happening on latest NetworkManager versions).
