Problems with adding network nodes to pasteboard

[marchenkoigor]

I recently found some exception in iMedia during drag of image from flicker.
Error log and exceptions are:

2012-03-15 15:55:24.854 iMedia2[72932:c03] Property list invalid for format: 100 (property lists cannot contain objects of type 'CFURL')

Problem occurs when we are trying to write metadata of object into pastboard at IMBObjectViewController.m

• (NSUInteger) writeItemsAtIndexes:(NSIndexSet_)inIndexes toPasteboard:(NSPasteboard_)inPasteboard function
{
...
// Keep all 3 items in sync, so the arrays are of the same length.
[fileTypes addObject:type];
[titles addObject:object.name];
[metadatas addObject:object.metadata];
...
wasSet = [inPasteboard setPropertyList:metadatas forType:kIMBPublicMetadataListPasteboardType];
...
}

Some options:

• Pre-process metadata dictionaries to remove/convert URLs
• Have a more defined system for deciding which properties go onto the pasteboard

Main problem is CFURL which, as I understood, coming from flickerAPI and i think best solution will be to add some sort of converter inside of IMBFlickrNode when we receive any metadata.
