Hey there,
For posterity, the fixing change is here. For 5.5, you could try and use the 5.6 binaries for a local build. Short of this, you’d need to apply either the fix above (via [Content removed] or wait until we get a 5.5 binary patch in (I’ll work with Henrik to see if we can get this - at the very least we can host the binaries on the Practical Debugging UBA page).
Stay tuned 
Edit: I’ve created a backport binary package here for 5.5
