[Vv] small vv bug

[Simon Rit]

Hi vv user,
The code is in vvImageReader.txx around line 150:

    } else {
      typedef itk::Image< InputPixelType, VImageDimension >
InputImageType;
      typedef itk::ImageFileReader<InputImageType> ReaderType;
      typename ReaderType::Pointer reader = ReaderType::New();
      reader->SetFileName(mInputFilenames[0]);
      reader->ReleaseDataFlagOn();

      try {
        if (mType == IMAGEWITHTIME)
          mImage=vvImageFromITK<VImageDimension,InputPixelType>(reader->GetOutput(),true);
        else
          mImage=vvImageFromITK<VImageDimension,InputPixelType>(reader->GetOutput());
      } catch ( itk::ExceptionObject & err ) {
        std::cerr << "Error while reading " <<
mInputFilenames[0].c_str()
                  << " " << err << std::endl;
        std::stringstream error;
        error << err;
        mLastError = error.str();
        return;
      }

At that point, it has already read the image information successfully.
Then, it reads the image data and is supposed to handle an exception
which I think doesn't work with qt... I don't have a quick fix for
this. Can you raise a bug in our brand new bug tracker?

You can assign it to anyone you dislike. We'll discuss it during one
of our regular vv meetings (we had one so far :-)
