digikam is trying to kill me and my computer

greets, folks . . . for more than a decade i've gone happily along, making pictures for a living, sorting them with a gnome application called gthumb (which meshes nicely with the gimp) and being generally happy. then the gnome people did what gnome people do: they improved gthumb to the point where it's utterly useless. they removed menus and scrollbars and committed other atrocities. so i thought i'd bite the bullet and try digikam, which is in many respects too much, just too much. it tries to do things that i do not want done. it insists on running a full inventory of all my pictures all the time -- gthumb was good about not doing this until it was asked to -- and generally behaves as if i'm a 14-year-old who wants to keep track of his million selfies. grrr. but i can live with that and i feel confident that after spending some time with it i can turn off much of the stuff i don't like and make it into something potentially more useful than gthumb was when it was useful, about one major version ago. but there's a problem: when i use digikam-trinity (0.9.6) within a few minutes i can hear my computer's fans screaming and when i run top i see that it's consuming more than 100 percent. any ideas how i can fix this or at least troubleshoot it? tia. -- dep Some pictures: http://www.ipernity.com/doc/depscribe/album
