--------------------------------

             Summary: EXC_BAD_ACCESS when using XHR bridge mode
                 Key: CB-1404
                 URL: https://issues.apache.org/jira/browse/CB-1404
             Project: Apache Cordova
          Issue Type: Bug
          Components: iOS
    Affects Versions: 2.1.0
         Environment: iPad 2, iOS 5.1.1
            Reporter: Tom Clarkson
            Assignee: Shazron Abdullah


When calling a plugin the app crashes on WebThread with EXC_BAD_ACCESS in WebCore::DocumentThreadableLoader::cancel.

This appears to be some sort of timing issue, as it does not happen on every call - I am seeing
it in an autosave function which makes lots of calls to PGSQLitePlugin. 

The error did not appear before upgrading to 2.1, and setting the bridge mode to IFRAME_NAV
restores the previous behaviour (no crashes, but odd scrolling functionality).

Setting the bridge mode to XHR_NO_PAYLOAD also seems to fix it - not sure if removing the
payload actually does anything different or just makes it fast enough that the timing condition
does not come up in normal app usage.
