The extension for video/quicktime should map to .mov, not .qt

[timcosta]

.qt is a deprecated extension, and while this was once accurate it means that looking up the mime for .mov and then getting the extension for the returned video/quicktime results in mismatched extensions.

Finally got a chance to look into this.

The problem is that the qt extension is named first in both mime-db and Apache mime types file.

This is where mime-db draws it's type info from, and it maintains the extension ordering. Both tje 'mime' and mime-types module prefer the first extension when mapping type -> extension. And I suspect neither I nor the mime-types authors are interested in special casing this in our code. The solution really needs to be in either mime-db or Apache's types file.

So... I'd suggest you file an issue with mime-db to that affect. You might also file a bug with the Apache project, but I don't know how willing they'll be to change there.
