The crash is occurring during Paint which doesn't tell us much about the

cause.

Do you have a test case that reproduces the problem ?

Something very specific must be happening for this error to occur so unless

we can reproduce it will be very hard for us to find the cause.

Are you using the latest SP ? What version of the product are you using ?
