Uncaught error when trying to filer.open() a directory

I'll try and patch this when I get a chance.

Did you get anywhere with this? I'm experiencing a roadblock so would appreciate a little help with how to patch or a workaround to check the file exists beforehand!

Doesn't look like I ever ended up fixing this, but I think what you want is to check something like:

if (!fileEntry.isFile) {
  // do something with opt_errorHandler
}
else {
  fileEntry.file(successCallback, opt_errorHandler);
}
