I am trying to download an email attachement from a Hotmail account. The name of the file contains german umlauts (html-codes : & o u m l ; & s z l i g ;).
The download failes with an errormessage like (originally in german, I try to translate) : "C:\DOKUME~1\hendrik\LOKALE~1\Temp\1xl4tzk-999.rtf could not be saved, because an unknown error occured. Please try to save into another folder." 
I tried it with different files (RichText (.rtf), PowerPoint (.pps)) and different names. The problem occures when the filename contains german umlauts.
Tried it on Windows XP SP2 (home and professional, german language).
original file name in this test case : "Größe.rtf"

Reproducible: Always

Steps to Reproduce:
1. send an email with an attachment with german umlauts in the filename to an hotmail account
2. try to download this file from the email by clicking on it
3.
Actual Results:  
"C:\DOKUME~1\hendrik\LOKALE~1\Temp\1xl4tzk-999.rtf could not be saved, because an unknown error occured. Please try to save into another folder." 

Expected Results:  
Display a dialog box, asking me what to do with this file (open with, save on disk/floppy,...) 

If you need an email, containing an example file, please tell me so.
there is a workaround: use MS Internet Explorer

So, this works fine for me on trunk (what will become Firefox 3), but fails on branch. Since we don't know what fixed this, and something like this probably wouldn't land on branch (it's only taking stability and security fixes), I'm resolving as WORKSFORME.
