Andrew Grieve commented on CB-1404:
-----------------------------------
I added some logging to the exec bridge to try and figure out what's going on.
The app is a bit hard for me to follow what's going on, and I'm having a hard
time figuring out if it's a cordova problem, or just a problem with your app.
Here are the logs with all bridge calls logged:

> EXC_BAD_ACCESS when using XHR_WITH_PAYLOAD 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: Andrew Grieve
> Fix For: 2.2.0
>
>
> 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.
