The client is trying to use COPY or MOVE command, but the copying fails for some reason and the cleanup code crashes. I can't reproduce this though, so would be helpful to know what exactly it's doing. So getting the gdb output for these commands (instead of just bt full) would help:

p *ctx
p *ctx.dest_mail
f 7
p (*_ctx).transaction.box.vname
p (*_ctx).transaction.box.storage.error_string
p mail.box.vname
