Hi Mathias,
I've tried installing the dev version and I think that that worked (this
is what 'about' shows).
QGIS version
2.15.0-Master

SpatiaLite Version

QWT Version

PROJ.4 Version

QScintilla2 Version

This copy of QGIS writes debugging output.
I started with a new project, added the tst shapefile again, repeated
the process of adding the virtual fields. The problem persists. Am I
overlooking something?
Thanks for your help!
