Profile provider not working?

[avalla]

Hello, I always receive a null reference exception when I use profile provider.

I tried custom class and web.config properties, no success.
If I debug I can see in Profile object that the properties always returns a null reference exception.
If I try to set a property I receive this exception:

[NullReferenceException: Riferimento a un oggetto non impostato su un'istanza di oggetto.]
MongoDB.Web.Providers.MongoDBProfileProvider.GetPropertyValues(SettingsContext context, SettingsPropertyCollection collection) in C:\MongoDB.Web\MongoDB.Web\Providers\MongoDBProfileProvider.cs:93
System.Configuration.SettingsBase.GetPropertiesFromProvider(SettingsProvider provider) +273
System.Configuration.SettingsBase.GetPropertyValueByName(String propertyName) +158
System.Configuration.SettingsBase.get_Item(String propertyName) +123
System.Web.Profile.ProfileBase.GetInternal(String propertyName) +36
System.Web.Profile.ProfileBase.get_Item(String propertyName) +77

The same configuration with aspnet profile provider is working fine.

Same problem here, there's no "Insert" anywhere in the code, so my guess is that the profile is never created or inserted into mongodb.
