uuups, no i did not realize, but in any way, it shouldn't be really segfaulting i believe. Check the available mem and prevent the opening of the file or such, but segfault, i doubt is a good thing. > > Steps to reproduce it: > > > > 1.

(i know about -g and stuff, but i have no idea how to get this into the efl automake stuff). But i remember there was a link on get-e.org (remembering now) how to get the stuff running, will have a look at that if need be. > > Program received signal SIGSEGV, Segmentation fault. > > 0xb7c0ed03 in evas_common_copy_pixels_rgba_to_rgba_sse () > > from /usr//lib/libevas.so.1 (gdb) bt > > #0 0xb7c0ed03 in evas_common_copy_pixels_rgba_to_rgba_sse () > > from /usr//lib/libevas.so.1 #1 0xb7c23d45 in > > evas_common_scale_rgba_in_to_out_clip_smooth_mmx () > > from /usr//lib/libevas.so.1 #2 0xb7c2bf1f in > > evas_common_scale_rgba_in_to_out_clip_smooth () > > from /usr//lib/libevas.so.1 #3 0xb7e3f74d in ??
