Works for me using r62123, downgrading severity.

Which article were you trying to import? From which wiki?

this articles I tryed to import, both failed

http://de.wikipedia.org/wiki/Opat%C3%B3w_%28Gro%C3%9Fpolen%29
http://marjorie-wiki.org/wiki/Kinder-Reha-Klinik_Haus_Herford

BTW: normal import works, only transwiki import fails

Was able to set up interwikis for both of those wikis and import those two articles (with full history and templates). Still worksforme.

well, I'm still testing.
upload_by_url works, so there should be no problem with getting content from external pages

I replaced
includes/Import.php
includes/specials/SpecialImport.php

with a clean version from SVN

the problem still remains, I've no idea what's the reason for this error. Please help, any ideas?
