Could the persons CCed to this bug because they themselves filed a bug please test if this push is affected and this one works as expected? Click at the bottom on "Artifacts" and download the target.tar.bz2. Thank you in advance.

This may or may not be the same thing as bug 1706452, but I can't reproduce this crash, so for now I'll assume this might be different, but we'll see if the fix there works here too, in which case we'll dupe the bugs.

I see a similar crash when running Firefox mochitest/reftest suite locally. It's a crash at gtk_init() and it generally means we can't open GdkDisplay. More details should be on terminal, may be "too many connections" or so.

this one fails and this one works

No crashes on Nightly since bug 1706452 landed.

Let's call this a duplicate then. :)
