[Bug] Error #2041 in custom board editor

I have no idea what caused this. It opened the board just fine the first time. I accidentally clicked "close" in the editor, returning to the MP lobby. I returned to the editor and clicked "open," and nothing happened. Here's the stack trace:

FF 28.0 on Windows 8.1.

On subsequent returns to the editor, I still can't open files. The open file dialog appears, but when I select a file the editor still leaves me with a blank board. No more stack traces though.

The second time, I had the client in Flash-fullscreen mode (not browser fullscreen) after clicking on the button in the MP Lobby and then entering the board editor. Flash was bumped out of fullscreen when the open file dialog appeared. (Maybe it's relevant, just want to give all the information.)

The board I was trying to open is attached.

After reloading the client, I can open the board file. I tested and I can open the file multiple times, and in Flash-fullscreen mode.

*shrug* chalk it up to cosmic rays...
