So Qt4Agg is used. However if the graphtool is imported, the interruption is still there:

In some distributions, the default theme used by Qt is QGtkStyle, which uses GTK itself to draw the widgets, so that KDE programs blend in seamlessly in GNOME. The problem is that this pulls in GTK+2 symbols, and causes this conflict. You can verify/change this by running qtconfig, and selecting for "GUI Style" something different than GTK+.
