This is coverity issue:

CID: 595
Checker: OVERRUN_STATIC (help)
File: base/src/source/blender/python/api2_2x/sceneSequence.c
Function: Sequence_setProxyDir
Description: Overrun of static array "&((((self)->seq)->strip)->proxy)->dir" of size 160 bytes by passing it to a function which indexes it with argument "248" at byte position 247

Wasn't using the size of dir it was using the sizeof the struct dir is in.

Fixed.
