Resolution of NSURL bookmark fails for an external drive in Yosemite

Question

In my cocoa app I use the following code to create a security-scoped bookmark from an NSURL that I got from an NSOpenPanel:

NSData *bookmarkData=[myURL bookmarkDataWithOptions:([NSURL instancesRespondToSelector:@selector(startAccessingSecurityScopedResource)] ? NSURLBookmarkCreationWithSecurityScope : 0) includingResourceValuesForKeys:(&NSURLPathKey==NULL ? [NSArray arrayWithObjects:NSURLVolumeIsLocalKey,nil] : [NSArray arrayWithObjects:NSURLPathKey,NSURLVolumeIsLocalKey,nil]) relativeToURL:nil error:&error];

and to resolve it, I use:

BOOL isStale;
myURL=[NSURL URLByResolvingBookmarkData:bookmarkData options:options relativeToURL:nil bookmarkDataIsStale:&isStale error:nil];

In Mac OS X Mavericks (10.9), this works fine when I create a bookmark for an external drive, like a USB stick. But in Yosemite (10.10), if the external drive is not mounted, the bookmark resolution doesn't return nil as it does in Mavericks. Instead, it returns a url that points to Macintosh HD (i.e. [myURL path] returns the string @"/"). I noticed that in this case isStale==YES.

Does somebody else experienced the same problem? Is this a known bug in Yosemite or am I missing some additional step to handle such a case? Is there a workaround?

This bug seems to be resolved in Mac OS X El Capitan.
