Specific zip file doesn't open in xarchiver

[jepler]

I noticed that some zip files were not opening in xarchiver. While I encountered this in xarchiver 0.5.4.20 on Debian Bookworm I verified it in 0.5.4.21 built from github.

The file in question is an artifact produced by github actions bundles.zip

It looks like the problem may be that unzip -Z -l shows "?" in the first column rather than "-":

unzip is from debian:

$ unzip --help

Your analysis is absolutely correct.
