Body
Could it be that you're calling <code>CFBundleCopyInfoDictionaryForURL</code> on the code signed helper tool? If so, it appears as though this function seems to break the code signing validity. (Presumably because <code>CFBundle</code> modifies the Info.plist data in memory, but this is just my guess.) The solution is to use <code>SecCodeCopySigningInformation</code> to read the helper tool's version info: <pre class="lang-c prettyprint-override"><code>-(NSString *) bundleVersionForCodeSignedItemAtURL:(NSURL *)url { OSStatus status; // Sanity check -- nothing begets nothing if (!url) { return nil; } // Get the binary's static code SecStaticCodeRef codeRef; status = SecStaticCodeCreateWithPath((CFURLRef)url, kSecCSDefaultFlags, &codeRef); if (status != noErr) { NSLog(@"SecStatucCodeCreateWithPath() error for %@: %d", url, status); return nil; } // Get the code signature info CFDictionaryRef codeInfo; status = SecCodeCopySigningInformation(codeRef, kSecCSDefaultFlags, &codeInfo); if (status != noErr) { NSLog(@"SecCodeCopySigningInformation() error for %@: %d", url, status); CFRelease(codeRef); return nil; } // The code signature info gives us the Info.plist that was signed, and // from there we can retrieve the version NSDictionary *bundleInfo = (NSDictionary *) CFDictionaryGetValue(codeInfo, kSecCodeInfoPList); NSString *version = [bundleInfo objectForKey:@"CFBundleVersion"]; // We have ownership of the code signature info, so we must release it. // Before we do that, we need to hold onto the version otherwise we go // crashing and burning. [[version retain] autorelease]; CFRelease(codeInfo); CFRelease(codeRef); return version; } </code></pre> To give credit where it's due: the vital piece of information regarding <code>CFBundleCopyInfoDictionaryForURL</code> came from <a href="https://github.com/nevir/SMJobKit" rel="nofollow">Ian MacLeod's <code>SMJobKit</code></a>.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
