Description Mattia 2019-04-28 09:44:17 UTC

STEPS TO REPRODUCE
1. Download breeze-icons tarball from https://github.com/KDE/breeze-icons
2. Try to open it with Ark, or select "Extract here" from contextual menu in dolphin

OBSERVED RESULT
Ark takes minutes to open the archive or extract the files, while from command line a "unzip breeze-icons-master.zip" takes a couple of seconds.

EXPECTED RESULT
Ark should have the same performance of command line.

Do you have the libzip plugin installed? Can you try again using that plugin?

What do you mean with "libzip plugin"?
I have libzip installed:
$ rpm -q libzip
libzip-1.5.2-1.fc30.x86_64

But in Ark settings -> extensions list I don't have libzip, only info-zip and p7zip (related to zip archves). Where I can found that plugin and how can I install it?

Comment 3 Elvis Angelaccio 2019-05-04 10:29:53 UTC

Weird, you should have it because libzip 1.3 is the minimum required version and you have 1.5. Please ask the fedora packagers why the libzip plugin doesn't get build.

Comment 4 Mattia 2019-05-04 16:20:01 UTC

The libzip plugin doesn't get created in Fedora RPMS because the .spec file misses libzip-devel as BuildRequires.
By using the libzip plugin the performance greatly improves, so I've reported to Fedora Bugzilla a request to enable it:
https://bugzilla.redhat.com/show_bug.cgi?id=1706358

I think you can close this bug here. Thank you.
