This is a followup to bug 826846. Once we get rid of the HomeScreen crash, I'm seeing the following when I follow the steps in bug 826846 comment 0. When I install the app for the 2nd time, it leaves an icon on the desktop, but it's application.zip file is missing (perhaps the install tries to delete the initial install then somehow fails?). If I click the icon, nothing happens. If I try to delete it, it won't delete, and when I reboot the phone, the icon has a little animation around the edges, like it's busy or installing or something, but I suspect it's just wedged somehow.

Noming only because the reinstall is causing dataloss and making it to remove the app. Normally I wouldn't block on reinstall issues, the dataloss and negative effects on the user's phone makes me think this could be worth blocking on.

Blocking, and over to Fabrice.

I'm having trouble reproducing this using the lasted gaia/b2g18 (with the patch for bug 826846). Jason, are you still seeing this?

It seems like something is going wrong the first time a packaged app is installed. Here's the log from 2 subsequent installs: I/GeckoDump( 580): XXX FIXME : Got a mozContentEvent: webapps-install-granted E/GeckoConsole( 794): [JavaScript Error: "TypeError: request.result.manifest is undefined" {file: "http://mozqa.com/webapi-permissions-tests/apps.js" line: 19}] I/GeckoDump( 580): XXX FIXME : Got a mozContentEvent: webapps-install-granted E/GeckoConsole( 794): [JavaScript Error: "TypeError: request.result.manifest is undefined" {file: "http://mozqa.com/webapi-permissions-tests/apps.js" line: 19}] I/Gecko ( 580): RemoteOpenFileParent: file '/data/local/webapps/{c80cd6b0-3dfa-4274-8aa4-187a6d2b9b79}/application.zip' was not found!

Fabrice came up with this idea, and it fixes the problem. Instead of trying to install a separate packaged app, we'll now update the already installed app with the same manifestURL. Fabrice, are there tests that this might break?
