BUG with PATCH: I can't reproduce this bug but when it occurred it would break e20 (seg fault), restart would lead to another seg fault.
It's a problem with the file manager and favourites.
This patch fixes it: http://haxlab.org/patches/e20_3_0_crash_fix.patch
It seems eina_hash_find can return a non-NULL 0 length result. Patch returns NULL if string is of 0 length and not NULL..
