Public bug reported:
Very similar to https://bugs.launchpad.net/bugs/147866
Extracting a zip archive, unzip creates empty files instead of
directories, when the listing does not contain trailing slash.
Interestingly, file-roller does work when extracting from archives like
this. I only encountered it now when trying to unzip from the command
line.
Here is the zipinfo listing for a zip file that will cause the bug to occur:
-----------------------------------------------------------------------------------------------
$ unzip -Z archive.zip
Archive: archive.zip
Zip file size: 264266 bytes, number of entries: 10
