GeForce GT 545/PCIe/SSE2
Broken: built from git source (master a6968e87f133)
Short description of error
In the VSE, generating a proxy for a scene strip or a meta strip will create a directory with a random name (using an uninitialized variable)
The error is obvious when reading the source here :
if seq->type is not SEQ_TYPE_IMAGE, and the sequence is not a movie sequence, then fname is uninitialized and a random directory is used.
