Ognyan are you using Michael's packages with version 1.10.20.0.1 ? Located on people.debian.org or the ones that were uploaded to the official archive ?
I've reinstalled my Hurd and the SEGV doesn't appear anymore, so my report is no longer reason for holding 1.10.20.0.1. But there is 1.10.21 upstream with long changelog entry, so I guess it's best the patch to be re-applied to this newer version.
