I should note that my product contains the following workaround code in its
awakeFromNib method, which might be what triggers the bug:

        // http://bugs.webkit.org/show_bug.cgi?id=16296 says:
        // "Calling [WebIconDatabase sharedIconDatabase] is enough to
instantiate the
        // global icon database, enable it, and result in icon loads.  Slapping
that
        // one-liner into your - (void)setupIconDatabase; method made it work.
        //
        // It really sucks that the only way to enable part of the API is to
use SPI
        // (granted, very stable SPI that's been around forever) but the
alternative is to
        // have the overhead of icon loads and multithreading for *all* WebKit
apps, which
        // is entirely unacceptable."
        @try {
                Class webIconDatabaseClass =
NSClassFromString(@"WebIconDatabase");
                if (webIconDatabaseClass != Nil) {
                        [webIconDatabaseClass
performSelector:@selector(sharedIconDatabase)];
                }
        } @catch (NSException *exc) {
#pragma unused(exc)
        }

Without this code, I never got any icon delegate messages at all. (For more
details on that, see the bug referenced.)
