User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

Opening the url http://www.rockbox.org/irc/rockbox-20050527.txt pops up Firefox'
download-dialog even though the webserving is specifying the mimetype
text/plain. The file includes 6 non-printable characters, but I don't believe
this warrants ignoring the mimetype specified by the server.

Reproducible: Always

Steps to Reproduce:
1. Open url http://www.rockbox.org/irc/rockbox-20050527.txt
2. That's it
3. There is no 3.
Actual Results:  
Firefox opens its "Save or open with" dialog.

Expected Results:  
Display the file-contents as text/plain as the server specified.

Same for Moz 1.7.8. I guess this is because the txt file contains some special
characters (non-printable) and the parser decides not to display it (thinks this
is some of the binary file types which are sent wrongly with plain/text).
Mozilla auto-sniffing decided that this can't be text. You can see that at the
text of the save as dialog in recent Mozilla trunk builds.

I think this is an edge case and will probably not fixed but confirming because
the developers must decide what to do with this bug report...

Could firefox be leaving it up to the user what to do since it believes that the
page is possibly corrupted (partial content)?
> Server: Apache/2.0.54 (Debian GNU/Linux) PHP/4.3.10-12

This is a known-buggy server that sends "text/plain; charset=iso-8859-1" for any
content it doesn't recognize.  We've been forced to work around such servers
after asking them for years to fix the bug.  See
http://issues.apache.org/bugzilla/show_bug.cgi?id=13986 and
http://issues.apache.org/bugzilla/show_bug.cgi?id=14095 for the discussion on
the Apache bugs.

Note, further, that sending the document in question as text/plain is in fact a
violation of the RFC that defines the text/plain MIME type, since the file
_does_ include said unprintable characters (which text/plain files are not
allowed to do).
