Thanks for a bug report. I move this to webkitgtk3, because it's the place where the crash happened. From the backtrace, the 'settings' variable is NULL for some reason, thus its dereferencing causes the crash.
I see exactly the same (SIGSEGV from the same place in the same file).
This only started for me after I installed the flash plugin /usr/lib64/mozilla/plugins/libflashplayer.so (which is a symlink to /usr/lib64/flash-plugin/libflashplayer.so. It looks like webkit automagically searches for browser plugins to load (confirmed with strace).
Here is the really weird bit. Copying /usr/lib64/mozilla/plugins/libflashplayer.so to ~/.mozilla/plugins stops the crashes. Yes, webkit finds ~/.mozilla/plugins/libflashplayer.so (lsof confirms this) but for some reason the bug depends on where the plugin is found!
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bug reports from releases that are no longer maintained.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'
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.
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
