slackware-current: hp-setup from hplip-3.23.12-x86_64-4 throws UnicodeDecodeError after selecting printer

When I try to add a printer using hp-setup to add a network printer I've successfully added in the past I get the error below.

Steps:

1. Run hp-setup from cli
2. Select "Network/Ethernet/Wireless network (direct connection or JetDirect)
3. Select my printer
4. Click "Next" followed by the crash

I see that there were patches applied to -4 to fix unicode errors, but they don't seem to work for whatever this is. I assume this is a system misconfiguration problem on my end, but I don't know where to start checking things.

Things I've tried:

• downgrading hplip to 3.23.12-x86_64-1 through 3 (same error)
• downgrading to hplip-3.20.6-x86_64-7 (ModuleNotFoundError: No module named 'cupsext')
• reinstalling hplip

The trace:
Code:HP Linux Imaging and Printing System (ver. 3.23.12)
Printer/Fax Setup Utility ver. 9.0
