This was a webkit bug, and is fixed in their ToT:

I don't know how to build WebKit with clang, but I think that I know what's
going on. We do call -[NSFileManager fileSystemRepresentationWithPath:] with a
nil argument, it raises an exception, and we end up returning from
-[_WebSafeForwarder forwardInvocation:] with an uninitialized result. 

This use of uninitialized result is a regression from shipping WebKit, I can
observe it with a gcc build - even though the form doesn't fail to submit for
