Bug ID: 523492
Summary: KZip fails with entry "/"
Classification: Frameworks and Libraries
Product: frameworks-karchive
Version First 6.28.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

DESCRIPTION
KZip fails to extract a ZIP file with an entry named "/".
It considers entries that "end with /" as directory, strips the "/" to get the
name. In case of "/" this results in an empty string and subsequent "Invalid
ZIP file, found empty entry name" error.
Ark opens the file just fine. I downloaded a directory from Dropbox which
resulted in a ZIP file like this, unfortunately I cannot share it.
STEPS TO REPRODUCE
1. Have a ZIP file with entry "/"
OBSERVED RESULT
"Invalid ZIP file, found empty entry name" error.
EXPECTED RESULT
File is read just fine
