borg mount fails with IO errors on access

System is fully upgraded (pacman -Syu) and rebooted.

Listing backup works:

borg list /run/user/x/gvfs/smb-share:server=nas,share=home/backups                                                                                                                                         :(

mounting a backup directory succeeds:

borg mount --foreground /run/user/x/gvfs/smb-share:server=nas,share=home/backups mnt

When I try to list a backup snapshot, borg or fuse crashes:
