[Koha-devel] 'Subroutine $FOO redefined' warnings in Koha

[Mason James]

hi Folks

i was looking at bug 8559, and spotted some unusable 'Subroutine $FOO redefined' errors
 http://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=8559

i did a google, and got some general info about the common problem,
but the info did was not enough for me to understand this specific problem in Koha :/


does anyone have an idea what is happening here?
are these warnings harmless enough to ignore? or do they reveal a bigger problem?

any ideas?
