Matlab access violation related to java/gstreamer

Hello,

I'm running Psychtoolbox 3.0.14 flavor beta (SVN 8301) on Windows 7, in Matlab 2013b.

I am getting an access violation when running a program that was working fine until yesterday (with no known changes to the software or hardware).

When I run the program in Matlab  with -nojvm it begins just fine, so I believe it is mainly a java problem. Downgrading the computer java version from 8.0.144 to 8.0.141 seemed to resolve the issue for one successful program run, but then the problem returned with the same error message. I'm also not sure whether or not the reinstall of the java version on the host system overrides what is being used on the virtual machine (apparently 1.7.0).

Any ideas what's going on? Error message below.
