I opened a link from gmail into linkedin, and immediately the tab crashed. This crash was caused by a rust panic.

The hunk of assembly which triggered the panic looks like:
   │0x7f50427862d1 <Servo_TraverseSubtree+273>                              callq  0x7f5042cad8f0 <_ZN14atomic_refcell15AtomicBorrowRef8do_panic17he0110f4b15c1a90bE>                                            │
   │0x7f50427862d6 <Servo_TraverseSubtree+278>                              lea    0x1de203b(%rip),%rdi        # 0x7f5044568318 <_ZN38_$LT$core..option..Option$LT$T$GT$$GT$6unwrap14_MSG_FILE_LINE17h89734ae7310│

Which makes me think that this is caused due to failing to grab an AtomicRefCell.

I guess this is a dupe of bug 1375902.

Now bug 1374175 has been closed. :mystor, could you please check whether the panic still happens or not?

I can load the page now, it doesn't seem to cause me a crash anymore. Thanks!
