This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
No faf report, so it's tough to get extra statistics. This is unlikely to be fixed in F20 since we are EOL soon, so closing. If anyone can still reproduce with F21+, please reopen
Bug #1175674, which has been opened for Fedora 21, looks like a duplicate of this one. The last line in bug #1175674 comment #0 is "Potential duplicate: bug 1147345". ABRT adds that line if it finds a duplicate bug but the duplicate is reported against different Fedora release.
