Hi,
Unfortunately, image is never nil. If no thumbnail file exists, an
NSImage object is returned which contains no representations (check
class NSBitmapImageRep, +imageRepsWithData:). Hence, no image is
displayed, not even the one for unknown file types.
Perhaps this has to do with multiple representations: imageRepWithData
returns NIL imageRepsWithData returns an empty array.
initWithContentsOfFile says though:
(from Cocoa Docs)
Return Value
An initialized NSImage instance, or nil if the method cannot create an
image representation from the contents of the specified file.
I think the culprit is _loadFromFile: it checks that the array is not
nil, instead it should check that the array is not empty.
I patched that, I dont't seem to have caused havoc elsewhere, please try
if it solves your problem.
Riccardo
