click on the image in this page: <html> <body> <a href="http://www.google.com"> <img src="http://www.google.com/images/logo.gif"></a> </body> </html> Dillo will segfault. Apparently, this is because there is no selectable content in the page. a_Dw_ext_iterator_new() is returning NULL at selection.c:152 selection->link = a_Dw_ext_iterator_new (it); selection->link_char = Selection_correct_char_pos (selection->link, char_pos); selection->link_number = link; ret = TRUE; So I tried a naive quick fix: selection->link = a_Dw_ext_iterator_new (it); if( selection->link ) { selection->link_char = Selection_correct_char_pos (selection->link, char_pos); selection->link_number = link; ret = TRUE; } else ret = FALSE; This just moved the bug elsewhere because dillo then segfaulted when I clicked the image and held the button down and moved off of it. Selection_switch_link_to_selection() expects a non NULL iterator.
