[Koha] Software error in memberentry.pl

[Administrateur]

Hello,

When I'm logged as a standard user and access to the
/cgi-bin/koha/opac-memberentry.pl
I have a software error :

Global symbol "$borrower" requires explicit package name at
/usr/share/koha/opac/cgi-bin/opac/opac-memberentry.pl line 190.
Execution of /usr/share/koha/opac/cgi-bin/opac/opac-memberentry.pl
aborted due to compilation errors.

The concerned line :
    # Send back the data to the template
    %borrower = ( %$borrower, %borrower );

I'm not familiar with perl so I don't really know what to do.

The problem doesn't appear when I log as the administrator and try to
modify user information with this command :

/cgi-bin/koha/members/memberentry.pl?op=modify&destination=circ&borrowernumber=...&categorycode=...
(but it isn't the same script so I guess that's why)

I use the latest Koha package from the apt.

The thing is that all my members are imported from a CSV file. I thought
it could be a problem but I have the same error even when I create a new
patron from scratch.

I use debian 8 stable all packages up to date.

Thanks.
