wine users - Mar 2011 - Gstreamer issue with Morrowind and Oblivion

In current git, I am able to launch Oblivion and Morrowind properly. However,
the games crash after the intro videos, both with the same output line.


Code:
err:gstreamer:push_data_init Obtaining buffer returned: -2



WINEDEBUG=+gstreamer revealed the following.
