-------------------------------------
Good observation @YuanKai, and possibly what is happening. What I'm thinking
is, since it is EXC_BAD_ACCESS, this usually means a message was sent to an
object that was de-allocated, which I believe is the .webView referenced in the
plugin (the only webView in the app). The Camera plugin is trying to send this
message to the webView property, and it crashes.
To prevent this crash, the application delegate should set the webView and the
webView delegate to nil in viewDidUnload
https://github.com/apache/incubator-cordova-ios/blob/master/CordovaLib/Classes/CDVViewController.m#L336
. This would prevent the crash, but of course all your workflow is gone, and
most likely not recoverable. Because of the memory purge, it should call
viewDidUnload, then viewDidLoad again, and your app should re-load again,
starting fresh.
Ignoring didReceiveMemoryWarning is just a stay of execution, ignored often
enough the iOS watchdog will kill your app anyway. Note that all running apps
(including Apple's) get this message, not just the current app.

> Key: CB-391
> URL: https://issues.apache.org/jira/browse/CB-391
> Project: Apache Callback
> Issue Type: Bug
> Components: iOS
> Affects Versions: 1.5.0
> Environment: 2 x iPhone 4S, iOS 5.1. Can't replicate on simulator or
> iHone 3GS with iOS 5.0.1
> Reporter: Richard Kimber
> Assignee: Shazron Abdullah
> Attachments: Wulvern_2012-03-27-141033_Richs-iPhone.crash

>
> getPicture has become very unstable on previously working code, affecting
> both Phonegap 1.4.1 and Cordova 1.5.0. Contributing factors, since last
> working build I have upgraded Xcode to 4.3.2 (from whatever the last version
> was) and iPhone to iOS 5.1 from 5.0.1.
> Memory warning is received on displaying camera, app crashes when you select
> 'use'. Restarting device usually resolves problem for a limited amount of
> time. Problem is intermittent and sometime difficult to replicate. Selecting
> from Photo library works fine.
> Options used:
> var options = {
> quality: 40,
> sourceType: Camera.DestinationType.FILE_URI
> };
> See
> https://groups.google.com/forum/?hl=en?hl%3Den&fromgroups#!topic/phonegap/ZLbw0s4JREs
> for more details.
> See attached for example crash log.
