Edit: I think the problem may have something to do with Optifine but I'm unsure

Can confirm, issue is still present in 0.0.6

When downgrading to version 0.0.4 of Canary I was unable to produce the crash again

fixed in 0.0.6 update.

Still got it in 0.0.6 https://gist.github.com/Gbergz/908c4cfd33d560437cec30c5b00989ed

Present in 0.0.6, here is the log
latest.log

I too confirm it's there in 0.0.6: Crashlog

should be fixed in 0.0.7.
