Hi, I thought I'd replied to this.
I think you might be barking up the wrong tree (or, likely, that there are multiple trees here). I could reproduce the segfault on Guix System and encouraged Jack to file this bug.
It's not foreign-distro-related. The process actually segfaulting is Guix, not svn, possibly due to a missing svn.
Kind regards, T G-R
