FWIW, we have a similar situation, but it's driven by a security need, and not a crash. When our app runs via Citrix, we are forbidden to ever show the regular windows "open" or "save as" dialogs. So we rolled our own. It's got a combo of drive letters (local drives only), folder selector (restricted to the approved drives), filename selector, and filename edit box.

For us, this gets around any active directory issues, and keeps security happy. And it keeps the users from trying to drop files into our filesystem or see things they shouldn't.

If they're not running in the sandbox, we show the regular windows file dialogs. A wrapper function allows us to call it from anywhere and leave the "sandboxed vs windows" decision in one spot.
