[imp] Some Clients don't see attachments with foreign characters

[Helga Mayer]

Hello,

As the subject already says, I wonder if the Mime Header encoding is correct.
If I send attachments with foreign characters in the filename, Pegasus cannot
display the attached file.

I'm using Horde Groupware Webmail Edition 1.2.6

Sending the same attachment with Thunderbird works fine for all clients.

I found a hint in http://bugs.horde.org/ticket/9212
but I can't get the patch. My browser says: "Malformed URL"
