hi,
as discussed on the #edevelop channel today, I had a segfault using
evas while doing load_size_set. before that I had a previously loaded
image and did file_set.
the segfault was caused by a null ptr in the image cache (below is the
gdb output). the src flags of the rgba_image was RGBA_IMAGE_NOTHING
and there was no check if the file was loaded before.
cedric proposed a solution that is attached in this patch, but he was
not sure if there could be any situation where a rgba_image with no
data set could not be a file. if this may happen this patch will be
wrong.
gdb output of the segfault:
#Program received signal SIGSEGV, Segmentation fault.
