UI leaves user guessing when nothing to print

[Jim Patterson]

When there's nothing to print, GLabels just closes the print dialog, and it can be difficult to figure out the problem.

This may seem silly but it can easily come up when you want to print a fixed page of labels. GLabels is quite good at this. You just fill the label template with what you want to print, and print a page (no insertion fields). However, there's a catch. The Merge Properties setting has to be 'None'. If not, then you might get a label per entry, or perhaps nothing at all. In my case, it was type VCards and Location was (None), so I got nothing at all.

GLabels (or maybe it's GTK) actually prints out a nice diagnostic, if you happen to be running from the command line:

(glabels-3:2697): Gtk-CRITICAL **: gtk_print_operation_set_n_pages: assertion `n_pages > 0' failed

It would be great if GLabels would put up an information dialog as well in this situation, since it's usually run as a GUI app.
