This fixes issue #412.

is it possible to add a test or update a test to make sure this doesn't regress?

[gabrielesvelto]

Sure, I'll try to add it.

let me know if you have a test case ready, or if you can modify an existing one that shows this change won't add any regressions, etc. thanks!

Yeah, I'll add a test here and provide a fix for issue #412 too later this year. I've been caught up in other stuff but I'll try to come back to this ASAP.

@gabrielesvelto no worries, just doing some triage this weekend/poking people :)
