QuickLook broken by BlocksKit

I've been enjoying using BlocksKit, but came across a surprising issue in one of my projects. When I attempt to display a .pdf or .docx file using QuickLook (QLPreviewController) the file is not displayed if BlocksKit is included in the project. If I remove BlocksKit from the project, these files are displayed correctly in the QLPreviewController. JPG attachments are displayed correctly whether BlocksKit is included or not.

To verify this, I created a new project with a single view controller that has a button that launches a QLPreviewController:

- (IBAction)click:(id)sender
{
    QLPreviewController *controller = [[QLPreviewController alloc] init];
    controller.dataSource = self;
    controller.currentPreviewItemIndex = 0;
    [self presentModalViewController:controller animated:YES];
}

- (NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller
{
    return 1;
}

- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"sample" ofType:@"pdf"];
    NSURL *url = [NSURL fileURLWithPath:path];
    return url;
}

In the initial project, when the button is pressed, the preview is displayed. Then, I added BlocksKit to the new project with CocoaPods with the following Podfile.

platform :ios
dependency 'BlocksKit',       '~> 1.5'

Then, I opened the newly workspace and ran my project again. This time the preview did not display. The preview controller is displayed, but the .pdf or .docx content never shows up.

This makes me suspect that one of the categories in BlocksKit is somehow interfering with the way QuickLook displays PDF and Word documents. Do you have any ideas what might be causing this?

Investigating. Sorry for the inconvenience.

Sorry for the delay, John, it was a rather easy fix! It'll be released today as part of BlocksKit 1.5.1.
