I started seeing this error this week, too:

Every single time I started anything with Wine, even wine regedit. I upgraded from wine-1.2 (stable) to wine-1.3 (dev) this week, trying to solve Steam issues, so I'm wondering if that's related.

The error is coming from the ".NET Runtime Optimization Service" service, which is installed with winetricks dotnet20. I have not solved the problem (presumably missing files or broken DLL overrides), but I have hidden the error by disabling the service:
1. Start wine regedit.
2. Go to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\clr_optimization_v2.0.50727_32
3. Find the "Start" parameter, it's a reg_dword set to 2.
4. Change the value from 2 to 0, which changes it from Automatic Start to Disabled.
5. Quit regedit.
6. ...
7. Profit!
