Bug 1080037

The output says it all:

# yast2 lan list
id      name,                   bootproto
0       Wireless 7260, Not configured
1       RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller, Not configured
Warning: unable to close filehandle properly: Bad file descriptor, <STDIN> line
        5 during global destruction (#1)
    (S io) There were errors during the implicit close() done on a filehandle
    when its reference count reached zero while it was still open, e.g.:
    
        {
            open my $fh, '>', $file  or die "open: '$file': $!\n";
            print $fh $data or die "print: $!";
        } # implicit close here
    
    Because various errors may only be detected by close() (e.g. buffering could
    allow the print in this example to return true even when the disk is full),
    it is dangerous to ignore its result.  So when it happens implicitly, perl
    will signal errors by warning.
    
    Prior to version 5.22.0, perl ignored such errors, so the common idiom shown
    above was liable to cause silent data loss.


I see this with yast2-network-3.3.6-1.1.noarch (sorry, I didn't have time for tumbleweed updates in the last weeks)

This bug is probably not depending on the hardware or config, therefore not attaching y2logs. If you need them nevertheless, please tell me.
