Bug 1172949

I just upgraded my desktop to Rawhide. Having problems starting the packaged Firefox, which is now GTK+ 3 on Rawhide. Here's the data I have so far:

1) The GTK+ 3 package does not work with my existing user account.
2) Moving ~/.mozilla and ~/.cache/mozilla does not help.
3) Starting with firefox -safe-mode does not help. (neither does 2) and 3) combined).
4) It doesn't work in GNOME or Xfce (so, not a desktop issue).
5) It *does* work with a new user account.
6) Upstream's static build - firefox-34.0.5.tar.bz2 - *does* work.
7) A rebuild of the Fedora package against GTK+ 2 instead of GTK+ 3 - all I did was change both %define toolkit_gtk3 lines to 0, bump the rev, and rebuild - *does* work.
8) Kevin Fenzi says the GTK+ 3 build works OK for him.

When I try to run it from the console, I see:

at which point it sticks. If I strace it, the main process is sitting at a FUTEX_WAIT. If I strace the threads, one of them seems to keep repeating this:

futex(0x7f9dbafc774c, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 223, {1418274200, 855170000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0x7f9dbafe63a0, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7f9dbafc774c, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 225, {1418274201, 855365000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0x7f9dbafe63a0, FUTEX_WAKE_PRIVATE, 1) = 0
futex(0x7f9dbafc774c, FUTEX_WAIT_BITSET_PRIVATE|FUTEX_CLOCK_REALTIME, 227, {1418274202, 855562000}, ffffffff) = -1 ETIMEDOUT (Connection timed out)
futex(0x7f9dbafe63a0, FUTEX_WAKE_PRIVATE, 1) = 0

but I couldn't get much further than that. Kevin's console output in his 'working' case does not contain all the same glib errors as mine - only the sys_page_size failures and the GtkSettings deprecation warnings, I believe.
