Comment 7 for bug 1580860

[Impact]

An old bug in Engrampa prevents users from creating
zip archives when the compression level is set to
maximum in the settings.

The fix for this issue is provided in the debdiffs
attached to the report.

The fix is already in Artful, and would be nice to
backport it to Zesty and Xenial as well. That bug
caused problems for years, especially if you don't
remember that you once set the compression level
to maximum. The error message doesn't really help.

[Test Case]

First, set the compression level to maximum, using
either dconf-editor or gsettings tool:

$ gsettings set org.mate.engrampa.general compression-level 'maximum'

Then try to compress any file(s) into zip archive.
The operation will fail with error message dialog,
and the archive won't be created.

[Regression Potential]

None. The fix doesn't affect any other features of
Engrampa (other archive types, other compression
levels, extracting, and so on).
