sis file name wrong building Qt Plugins for Symbian^3

I have the attached pro file for a Qt Plugin project. When I load this project up and build it, it actually creates a stubplugin.sis, but the auto-generated path in the project's run settings shows as stubpluginind.sis. So when it deploys it attempts to install stubpluginind.sis but it actually created stubplugin.sis.

Other non-plugin pro files are fine.
