Two schools of thought I've heard on plate cracks:

1)  Run the other direction!  Or at least, make no attempt whatsoever to do
anything with the string tension except to quickly and systematically drop it
all (to at least an octave below tension).

2)  Assess if the crack actually is located someplace that does brace against
tension.  Sometimes one appears in the tuning pin region and has no apparent
effect on stability.

Your crack, however, continues south of the pressure bar and you have a pitch
discontinuity as evidence that it does matter.  Go to (1)!
