Description

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.1) Gecko/2008071718 (Gentoo) Firefox/3.0.1
Build Identifier: 1.9.0.1

Problem occurs when update is marked as minor. Xulrunner is not downloading pointed update, but it creates dir structure (updates/0), and update.status file. Status is marked as downloading.

Reproducible: Always

Steps to Reproduce:
1. Create update.xml, mark update type as "minor", and put it on update server.
2. Set preferences as described on http://developer.mozilla.org/en/docs/XULRunner:Application_Update, change app.update.url to your update server and app.update.interval to 10 seconds.
3. Run application and wait.
Actual Results:  
Update is marked as downloading, but .mar file is not even created, connection is broren with tcp rst flag (sniffed with tcpdump and wireshark).

Expected Results:  
Xulrunner should download file and inform about available update.

I've done some research, and I find out solution. Problem seems to be in nsUpdateService.js file. When DOWNLOAD_BACKGROUND_INTERVAL is set to 600 (default), or even 1, download won't start. But when i set it to 0, xulrunner downloaded file normally and informed me about available update.
