The problem seems to have started in 11.0 beta. It's in all rc and also in the final. I never tried the nightlies of 11 tho. In 10.1 the problem does not occur.
Here's my log:

I start xbmc in portable mode (-p).
The workaround is putting advancedsettings.xml in the userdata folder. The advancesettings.xml contains this:
<advancedsettings>
<loglevel>1</loglevel>
</advancedsettings>
Thanks to RazorFR for that info.
