luci fails after installing luci-app-qos through web interface

[anonymous]

Steps to reproduce:

1. Go to the System > Software tab
2. Update the package lists
3. View available packages
4. Type 'qos' in the filter without the quotes
5. install luci-app-qos

Result:
After a minute or so, the following error text is served back to the browser:

/usr/lib/lua/luci/dispatcher.lua:449: Failed to execute call dispatcher target for entry '/admin/system/packages'.
The called action terminated with an exception:
/usr/lib/lua/luci/template.lua:105: Failed to execute template 'admin_system/packages'.
A runtime error occured: /usr/lib/lua/luci/ccache.lua:81: error loading module 'luci.tools.webadmin' from file '/usr/lib/lua/luci/tools/webadmin.lua':
	/usr/lib/lua/luci/tools/webadmin.lua: bad header in precompiled chunk
stack traceback:
	[C]: in function 'assert'
	/usr/lib/lua/luci/dispatcher.lua:449: in function 'dispatch'
	/usr/lib/lua/luci/dispatcher.lua:195: in function </usr/lib/lua/luci/dispatcher.lua:194>

After this, /cgi-bin/luci returns totally empty HTTP responses, even after a reboot. In order to fix it, I have to reflash using sysupgrade, since I don't know how to debug the problem any further.

Installing from the command line shows that my system was subscribed to an old opkg repository version:

# opkg update

Inflating http://downloads.openwrt.org/backfire/10.03/brcm47xx/packages/Packages.gz.
Updated list of available packages in /var/opkg-lists/packages.

# opkg install luci-app-qos

I'm guessing that the web interface tells opkg to ignore these errors and install anyway, resulting in a broken system. It would also be nice if the upgrade process were to update old versions of the OpenWRT repository URL in /etc/opkg.conf, to avoid this being an issue. Perhaps this bug should be split into two, to handle each of these issues.

There is nothing left to fix for us. opkg.conf is not marked as config file anymore and a simple reset to defaults will fix this issue too. Alternatively you can manually fixup opkg.conf after restoring old backups to make sure it points to the correct repo.
