Fix crash when arguments().mimeType() is an invalid mimetype name.

I have a JIRA bug report with a PDF attached, and mid-clicking the PDF
in konqueror leads to opening an okularpart with mimetype="application/x-octet-stream"
(the x- in there is very unusual, and unknown to shared-mime-info).
Fixed with null pointer checks.
