For an applet I'm writing, I'm using the canvas to draw a little dial thing. The dial is rendered using an ellipse and a line (with some text over the top), but for some reason whenever I add the line to the canvas, I get a segfault. If I comment out the code for the line, it works fine with just the ellipse and text. I'm running Debian unstable, with libgnome v1.4.1.4, and libgnomecanvas v1.109.0. (the full libgnome* version listing is at the end of this mail) The code I'm using is basically a copy and paste from a quick ap I wrote to the test canvas - which works fine. At least, when I changed from gtk_init() to gnome_init() - using gtk_init() resulted in an error about not being able to find the line type in the ancestry. I'm using applet_widget_init() for the applet - is there something else I should be using instead? The code to add the line is: canvasitem = gnome_canvas_item_new (GNOME_CANVAS_GROUP(group), gnome_canvas_line_get_type(), "fill_color", "yellow", "width_units", (double) 3.0f, "last_arrowhead", TRUE, "arrow_shape_a", (double) 5.0f, "arrow_shape_b", (double) 4.0f, "arrow_shape_c", (double) 3.0f, NULL); The points are filled in later by a timer callback; I used the same method in the test app without problems. Here's a backtrace of the crash. Interestingly, it happens once the applet is set running (with applet_widget_gtk_main()), not during the above call. gnome_canvas_line_get_type() returns a value (0xE015) without any problems...
