Hi guys I am currently developing a module which I keep re-installing on one of my test sites and from time to time a get greeted with this object reference exception exception on a page refresh.

The browsers is reporting the following stack trace:

[NullReferenceException: Object reference not set to an instance of an object.]
DotNetNuke.Entities.Users.UserProfile.ClearIsDirty() +174
DotNetNuke.Security.Profile.DNNProfileProvider.GetUserProfile(UserInfo& user) +2152
DotNetNuke.Entities.Profile.ProfileController.GetUserProfile(UserInfo& user) +173
DotNetNuke.Entities.Users.UserInfo.get_Profile() +185
DotNetNuke.HttpModules.Membership.MembershipModule.AuthenticateRequest(HttpContextBase context, Boolean allowUnknownExtensions) +2710
System.Web.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() +91
System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) +164

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.34280

EventViewer is reporting the following stack trace:

Which is then followed by a series of stack traces until the application recovers.

It is not a huge problem as DNN recovers after a few minutes and it doesn't happen all that often. But still I am curious to know if anyone came across the same issue?

By the way I am developing under DNN 7.4.2
