Description
Setup: One custom abstract item model, two attached proxy models that do filtering and ordering.
Up until Qt 4.6.3 this worked perfectly, i.e. single row insertions and row deletions as well as full model resets worked as expected. From Qt 4.7.0 onwards (tested with 4.7.0, 4.7.1 and 4.7.3) I however get many crashes, on either action. A simple full model reset already triggers the first one:
