Moodle 1.8 Beta + (2007021401)
When trying to use /admin/langimport.php, there happened nothing, first. Then I remembered adding our proxy, and now displaying the language selection boxes works fine. When selecting a language and clicking "<- Install selected language pack", nothing happens for a long time. With Debugging set to "DEVELOPER" I get the following output after 60 seconds of wait:

"
XML-Verarbeitungsfehler: Kein Element gefunden
Adresse: http://localhost/moodle/admin/langimport.php?mode=2
Zeile Nr. 258, Spalte 1:
^
"

Translated something like:
"
XML-processing error: no element found
address: http://localhost/moodle/admin/langimport.php?mode=2
line Nr. 258, column 1:
^
"

This error led me to the component_installer, and that seems to use "file_get_contents" to download the language-pack, but I was unable to find something like "proxy_url" in admin/langimport.php - I think the component_installer does not incorporate the proxy-rules.

Any comments if I did something wrong? Any fast workaround for installing a langpack locally? Thanks for this great program!
