After some investigations it seems mc isn't able to handle zip files with entries which have broken Unix file attributes. Whereas the zip file itself can be extracted without any problem.

'''zip with valid Unix permissions'''

{{{
$ /usr/lib/mc/extfs.d/uzip list foo.zip
drwxrwxrwx 1 1000 1000 0 03/27/2015 04:39:26 addons/
}}}

{{{
$ zipinfo foo.zip | grep Unix
file system or operating system of origin: Unix
Unix file attributes (040777 octal): drwxrwxrwx
}}}

'''zip with invalid Unix permissions'''
{{{
