Import errors are not showed

when there is a user with same email, there is no error about that user that isnt processed,
for instance, it only says:

filename date processed imported errors mode
users.txt 8 Nov 2005 - 9:40am 4 3 0 imported

in earlier version would say:

filename date processed imported errors mode
users.txt 8 Nov 2005 - 9:40am 4 3 1 imported

and when i click on errors info would show
