           Summary: REGRESSION (r100311): YummySoup app crashes when
                    trying to print
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P1
         Component: Page Loading
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: ap at webkit.org
                CC: abarth at webkit.org, japhet at chromium.org


Steps to reproduce: 
1. Launch YummySoup! trial from http://hungryseacow.com/YummySoup!.zip
2. Hit Cmd+P to open print dialog.

The issue here is some bad code in SubresourceLoader::releaseResources(). Instead of releasing resources as promised, it does a number of unrelated things. Specifically, call to m_document->cachedResourceLoader()->loadDone() results in a delegate callback happening in an inconsistent state. When a client does something from this delegate call that touches this SubresourceLoader (e.g. starts a new load), all bets are off.

Nate, would you be up to cleaning this up to fix the regression?
