167670 - Save/Run dialog names wrong MIME type

Status: RESOLVED WONTFIX

(Core Graveyard :: File Handling, defect, P4)

Description

[Calvin Spealman]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020826
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020826

It reports the correct MIME identifier, but reports the readable name according
to the file extension.  Try downloading the binary with the HTML extension at
the link provided.

Reproducible: Always

Steps to Reproduce:
1. Goto the MIME test page
2. Try to download the Binary with the HTML extension

Actual Results:  
Save/Run dialog appeared asking if I would like to save or run the file and
reported it: "HyperText Markup Language" (application/octet-stream)

Expected Results:  
Should have displayed "Binary Executable" instead of "HyperText Markup Language"

I did this on purpose, actually....  In the average case doing the extension
lookup once the mimetype lookup has failed is helpful.  When it's not, we get
this sort of issue....

Taking; this will likely be fixed when I implement getFromMIMETypeAndExtension().

biesi, what do you think we should do here?  What behavior would be "correct"?

In general, I'm tempted to leave our behavior as-is.

I agree - the file extension's description is usually helpful when the type isn't.

Done.
