EXCEPTION_ACCESS_VIOLATION (0xc0000005) using WebView and WebEngine

I load a web application in JavaFX web browser, but when I use the web application, I can see in the task manager that the memory grows and finally the application crash reporting an error report file.
The web application load images in Base64 format.
The web application functions well in chrome and mozilla browsers.

I have prepared a test case to download in the link: http://download.mibox.es/testcase/TestCaseJira.zip
With the error.log, the sources and a test case with a .bat archive to run.
The steps are:
1. execute TestCase/run.bat
2. Wait the progress bar finish and the little images are loaded on the left side.
3. Open the task manager and locate the process.
4. Click on the first litte image on the left, wait the progress bar finish and all the images are loaded.
5. Click on every little image on the left, the application will crash.
6. If the application don't crash, try again, and play the images with the mouse wheel and apply an effect to the image.

The images are DICOM files.
