Midnight Commander in Ubuntu - not opening zip and jar files

Just a really weird dicovery:

I was recently getting problems opening zip (and jar) archives on Midnight Commander (on my Xubuntu 15.04 Desktop). I repacked soem jars and some opened but most didn't. Today I was dicovering that also zip-archives were not browsable anymore. Then I stumblen upon this post: https://www.midnight-commander.org/ticket/2623 (created 4 years ago). It basically tells you to check /usr/lib/mc/extfs.d/uzip and change

my $op_has_zipinfo = 0;


my $op_has_zipinfo = 1;

Voila. Everything works again.

Hope this helps anybody.
