from Alexander Kuznetsov (alexk) with edits. From the report: Blender assumed that all files are .blend as retval = 0; Now retval is initialized as file cannot be open (-1) for gzopen fail and directory case retval = -2; is defined for not supported formats This must be assigned before #ifdef WITH_PYTHON because this part can be missing Finally retval = 0; if it is a .blend file --- also made other edits. - exotic.c's blend header checking was sloppy, didn't check data was actually read, only checked first 4 bytes and had a check for "blend.gz" extension which is unnecessary. - use defines to help readability for BKE_read_exotic & BKE_read_file return values. - no need to check for a NULL pointer before calling BKE_reportf(). (will just print to the console) - print better reports when the file fails to load.
