Missing resources/theme/images/theme.html

Using Cmd v3.0.0.250, I get the following error when running 'sencha app build':

....
[INF] Build complete
[INF] Building theme
[INF] Capturing theme image
[ERR] BUILD FAILED
[ERR] com.sencha.exceptions.ExProcess: phantomjs process exited with code 100 :

Any ideas on what I can do to resolve this problem?

I am using Ext JS version 4.1.3 and the default theme.

By reverting to ExtJS version 4.1.1a, it seems to work. Does 'sencha app build' not work with the latest ExtJS version? If so, what are the plans to fix this?
