This one fixes existing profile I had on my desktop that appears to be not
working anymore.

This seems to be reproducing even on empty user_data_dir on desktop builds so I
won't commit this CL till root cause is found. Meanwhile this CL maybe used to
run debug builds w/o hitting DCHECK in UserImageLoader.
