1376144 - All tabs always crash with: cannot send/recv, SinkInfo contains invalid flags

Status: RESOLVED DUPLICATE of bug 1375873

(Firefox :: General, defect)

Description

[Ralf Jung]

Firefox Nightly "Version 56.0a1 (2017-06-24) (64-bit)" Linux moved itself into an entirely broken state -- when I open a new tab and go to a website, it just shows "Your tab just crashed.".  When I click "Restore", the tab crashes immediately again.  All my existing tabs that got restored when FF launches show the same behavior.

How I got here:
* Firefox Nightly was running just fine.
* Then my machine froze, I had to use Magic SysRQ to hard-reboot it.
* After coming back from the reboot, nightly behaves as described above.

I launched nightly on the console, setting RUST_BACKTRACE=1, and it shows this (excerpt):
