Why do I get "openerp.modules.module: Couldn't load module web" after reboot?

I just updated some packages of my Ubuntu server (nothing OpenERP related as far as I can tell) and rebooted it as there were also some kernel updates. After that I saw "No handler found." when I went to the webinterface of my OpenERP installation. Having a look in my openerp-server.log I saw "openerp.modules.module: Couldn't load module web". I guess that's responsible for the "No handler found" message but why the heck couldn't it load the web module?? OpenERP was running just fine for several month now and survived many system updates and reboots (I excluded OpenERP itself from the apt-get update routine as I don't like the idea of getting a untested nightly version every day...). And there was nothing changed, I checked the addons path (correct and all web and web_* directories in place), I checked the file permissions and ownership (correct and openerp may still access and modify all of its files) and I checked if some file would have been modified lately (not the case).

After those checks I played a little around with the addons path and updated openerp manually to the latest nightly version. This didn't change anything.

So what can I do?

Here is the log file with my original OpenERP version and after the update. I also tried debug mode but that didn't reveal anything more useful than that. I also guess the "report.sale.order"-problem you see in the log has nothing to do with the problem also I'm not sure and I wouldn't know how to fix it:

Reflecting on my own question I solved my problem. It indeed was due to the duplicated "report.sale.order". Checking the addons in the addon path I already noticed before that one is out of order: some "sale~1" which got created after the other folders (and was not updated by the update to 7.0-20140205-002759 either). There also was a second "sale" folder which I guess is the original. Removing the "sale~1" folder from the addons directory solved the problem. Now also the web module gets loaded again. I have no idea how this "sale~1" got there. I guess I have installed/updated some OpenERP addons after the last reboot which caused this and since then not rebooted the system or OpenERP so that I noticed the error just now. But as long as my installation and DB are working now (and so far it's looking good) I don't mind.
