I'm not clear what is supposed to happen with default
settings and use of attachment link in Compose window.

My users have begun to report this error happens with word
docs. Images or a txt attachment are fine and view inline
in a new window.

I'm running horde 5.1.5 and imp 6.1.5

I'm OK with any behavior other than an error.  If it did a download
like the Drafts folder view, that works too.  The error is specific
to using the link in the Compose.

I've tried including or not including the magic.mgc configuration,
with web server
restart.  No difference.  The test script earlier in this thread
does work for a .doc file when run from php on Linux shell.

$ php /tmp/test.php

application/msword

Clicking on the word doc link in a compose window, for Windows client,
Linux client, IE or Chrome,

I get this error:

A fatal error has occurred

Could not display attachment data.

I'm using mime_drivers.php as shipped, no mime_drivers.local.php
nor mime_drivers.d/

I don't intend to set up abiword or whatever in mime drivers.

I'd think if the user has an application, it should launch the helper app
as it does on any regular web site.
