Hello again and thanks for your informative answer! The problem had already been filed upstream (bug 580055, https://bugzilla.gnome.org/show_bug.cgi?id=580055 ). It is caused by the program not handling correctly not having enough sudokus to print.
An ugly work-around: 1) Run dconf-editor. 2) Search for gnome-sudoku 3) Make sure that "generate-endlessly" flag, and the "generate-target-<difficulty>" flags corresponding to the level of the sudokus you want to print are set. 4) Close dconf-editor 5) Start gnome-sudoku. Leave it running a few minutes, to allow it to generate enough new puzzles. 6) Print the sudokus.
