Just came across my files for this bug from 0.59.
Walking into clipped water made my character get stuck and sink without dying.
Have tried to verify it for .60 but died several times on my way to there.
Here's the location (060 027): http://imgur.com/G7BvwH1

Maybe you can confirm/resolve the issue!?
