CRASH (dhvis loading large dataset)

_From [bruen...@google.com](https://code.google.com/u/109494838902877177630/) on August 20, 2013 11:37:46_

I had the dhvis from Branden (no revision # since not yet committed) load the remoting_unittests dataset that I earlier sent to Branden. dhvsi crashes. Here is the callstack. Unfortunately the Qt5 installation doesn't ship with debug info, and dhvis.dll seems to not have debug info (will investigate -- something's not right in its build settings):
