These don't have enough context to be translated properly:

#: ../lib/MusicBrainz/Server/Form/Utils.pm:132
#: ../lib/MusicBrainz/Server/Form/Utils.pm:155
msgid "Other"
msgstr ""

#: ../root/edit/search_macros.tt:155
#, perl-format
msgid "on"

#: ../root/relationship/linkattributetype/common.tt:19
#, perl-format
msgid "none"

#: ../root/components/common-macros.tt:591 ../root/edit/details/macros.tt:28
#, perl-format
msgid "in

"

This appears to be cut off:

#: ../root/user/profile.tt:49
#, perl-format
msgid ""
"User accounts must be more than 2 weeks old, have a confirmed email address,"

What does this even mean?:

#: ../root/release/merge.tt:88
#, perl-format
msgid ""
"This requires that mediums over each release have corresponding track "
"counts."
