This looks a lot like bug 926658, but not exactly. Though I'm not totally sure all the duplicates of bug 926658 match it perfectly either.

[Bilal Akhtar (bilalakhtar)]

Definitely looks like bug #926658. The top of the stacktrace is different though, but that may just be due to difference in Unity versions.

Moreover, that bug is from Unity 5.2, so major differences in the stacktrace are to be expected. I think this is a duplicate, but Daniel, what do you think?

[Walter Garcia-Fontes (walter-garcia)]

Bug #926658 has been fixed. I will close this bug, if the bug is still being seen please feel free to reopen by marking its "status" to "confirmed" again.
