+    MimeTypeFinderJob: the StatJob details should include the mimetype
+    
+    Apparently we forgot to specify that we want the UDS_MIME_TYPE field in
+    the statFile() method (both when it lived in OpenUrlJob and when it was moved
+    to MimeTypeFinderJob). And now there is a dedicated StatJob flag, StatMimeType,
+    that we can use.
+    
+    Not passing KIO::StatMimeType when creating the StatJob meant the code always
+    used a get job to determine the mime type, which mean that e.g. opening an
+    ISO file from Dolphin, which supposedly just needs to launch Ark, had the
+    whole file read into memory, which means that opening a couple of ISO's and
+    you're out of memory...
+    
+    Thanks to sitter for doing a big chunk of the investigative work in the bug
+    report.
