All that is, is a notification of the error and that Windows wants to send it to Microsoft for review.
Basically when we get the error, it is placed in a virtual bucket. When the bucket reaches a certain point (the number of incidents that have occured) then it is moved forward to resolution.
Now that doesn't mean it patch won't be coming soon but just an explanation of what the process is.
Now to your problem.
rundll32 errors can be caused by a number of things. There are a multitude of 3rd party products that hook into it as well as Microsoft products. The question I have is, what were you doing when the error occured? Also, how often does it happen and when does it happen? during bootup? when opening a control panel applet? when printing? when opening Internet Explorer properties?
