Comment 8 for bug 1483615

Since you only have one UPS, I would recommend removing the extra "-x" options (this prevents problems down the road if a new kernel assigns a different bus number). I believe the regex matcher is case-sensitive, so the "051D" does not match.

Interestingly enough, we did have another recent unreproducible report of an APC-related segfault that cleared up after a reboot: https://github.com/networkupstools/nut/issues/252 but it would be interesting to find out why the string descriptors are sometimes not available.
