Can't fetch by chemical name

I believe this to be a bug with Avogadro

Environment Information

Avogadro version: 1.2.0
Operating system and version: Win10 Version 1909

Expected Behavior

Molecule such as “butane” to appear after fetching by chemical name.

Actual Behavior

Nothing appears and the file name does not change.

Steps to Reproduce

Fetch by chemical name.

I have tried reinstalling Avogadro twice and even installing Avogadro2, and nothing has worked.

Update: No “Fetch” function works at all. I can not even use “Fetch by URL.”

I cannot confirm the bug – Avogadro 1.2 works fine for me. My setup: Avogadro 1.2.0, installed under Wine in ArchLinux, Open Babel 2.3.90 (do you have it?).
