Description of problem: wanted to try the wayland session option. it just drops me back to gdm login. my hardware is surely in the logs somewhere, but anyway my guess is the intel HD 4600.

The same problem Intel GPU.
Another me. Also intel gpu. driver=i915
Same issue here, AMD 7850, open source drivers.
Same issue here, GeForce GT 610, open source drivers.
I also have this issue, with Intel HD 4600 graphics. This occurs both on my install which is an upgrade from Fedora 20, and with a Fedora 21 livecd with the appropriate packages installed.
I have finally logged to Gnome/Wayland (but under Debian, but workaround could also work on Fedora) when I unloaded acer_wmi module. Similar bug, where I found workaround: https://bugzilla.redhat.com/show_bug.cgi?id=1147884
BTW I have filled bug report upstream, because a it affects also Debian 8 Jessie with Gnome 3.14: https://bugzilla.gnome.org/show_bug.cgi?id=744545
I hit this crash with a Thinkpad W540 and do not have the acer_wmi module loaded. So it's not specific to just that kernel module. I can test with the thinkpad_acpi module unloaded (though that provides some quite useful functions).
I am not a Gnome developer, but I think it could be helpful. Currently I can run Gnome/Wayland on Debian and I have: root@debian:/# lsmod | grep -i -e wmi -e acpi wmi 17339 0 root@debian:/#
Have you try the workaround that works for F22?
Look like these are duplicates https://bugzilla.redhat.com/show_bug.cgi?id=1200439
Same issue, when closing "System settings" window, GNOME crashes
This message is a reminder that Fedora 21 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 21. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '21'. 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 21 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.
