           Summary: [Qt] Lookup mimetypes using QMimeDatabase
           Product: WebKit
           Version: 420+
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: allan.jensen at digia.com


With the recent addition of QMimeDatabase in QtCore we can get rid of the static table of mimetypes and extensions which is constantly in risk of becoming outdated and instead use QMimeDatabase which uses the system mimetype database if available. 

Note that to begin with this should probably be restricted to filename detection only. Detection by content has historical had some security issues due to some loaders not verifying against context.

Benifits should be better detection of downloaded files (offers of applications), and ability to recognize common aliases for supported mimetypes.
