Thank you for posting the report ID. Did find a partial error log with that ID. Even though we did not get a complete error log it did show Avast coming up in it a bunch. To see if this is related to Avast add Diablo III to Avast exception list and see if temporarily disabling Avast helps.
If the crashing still happens, please post a DxDiag and Diablo III Error Logs. Paste the DXdiag and Diablo III Error Logs into the post, select and highlight everything you just pasted, and hit the "code" button (</>). That'll make the information much more readable.
