Downloading attachments (bug?)

[Cort Tompkins]

Hello,

I've had issues downloading attachments with the last few 2.2.X releases 
(including 2.2.5) and I'm wondering if this is a bug.  By default IMP generates 
a URL (on the message page) of the following form to save an attachment:

http://mysite.com/horde/imp/view.php3/ATTACHMENT.EXT?urlvars=blahblah

Clicking on this link gives me an "Internal Server Error" (which, because of 
the way I have PHP setup, may be the same as a 404) even before the save dialog 
appears.

However, if I modify /horde/imp/lib/mimtypes.lib to generate the URL in the 
following form everything works great:

http://mysite.com/horde/imp/view.php3?urloptions=blahblah/ATTACHMENT.ext

I've verified this problem using both IE 5.5 and Konqueror 2.1.1.  My website's 
running PHP 4.0.5 with IMP 2.2.5 on a FreeBSD 4.1.1/Apache 1.3.14 shared 
server.  

Below is a diff of the change I made:
