#191 0-pointer crash in mlt_properties_find mlt_properties.c:487


I checked out git master, compiled it on an openSuse 12.3 64bit.
When I now start kdenlive it crashes with the following bt.
I've probably done something wrong but the code should check a pointer before dereferencing it (self == 0 here):

Program received signal SIGSEGV, Segmentation fault.
