Hi Jeremy,

after upgrading gdk-pixbuf to

ii  gir1.2-gdkpixbuf-2.0:amd64 2.44.5+dfsg-3
ii  libgdk-pixbuf-2.0-0:amd64  2.44.5+dfsg-3
ii  libgdk-pixbuf2.0-common    2.44.5+dfsg-3

geeqie still crashes when scaling the image to 1 and moving it.
A gdb run results now in:

$ gdb geeqie
...
(gdb) run
...
