Tor Browser won't open with OpenVPN

We've had multiple users say that they're unable to start Tor Browser when trying to use it behind various OpenVPN-based VPNs, including ClearVPN and HideMyAss. Even with antivirus and firewall software disabled, the experience seems to be that a Firefox window won't even open. On Windows 7, the mouse cursor will spin for a moment, then nothing will happen. Hence these users are unable to provide a Tor log.

Exact steps to reproduce would be good. (ideally without having to pay something/give personal details away to some sketchy VPN provider)

Here are the steps as I understand them:

1) Follow the instructions provided by a VPN provider to set up your VPN connection. Test that the connection works. Hypothetically this could be also be done by setting up an OpenVPN instance on a server of your own and connecting to it, but the time trade-offs of learning how to do that properly may not be worth.

2) Download and install Tor Browser. Attempt to start it from behind the functional VPN.

Note that asking users for screenshots of this happening has not been that fruitful because they insist there's nothing to show. "It's just my desktop." If I understand the situation correctly, I think a Firefox process will start then immediately die.

Does it matter which Tor Browser they are using? Is this a new 4.0 thing or does that happen with older releases (3.5, 3.6, ...), too? (older ones can be found on
