I'm running NothingReal's (now apple's) Shake 2.4 under wine 20021007.  I can 
cause a crash by launching shake, creating a "colorcorrect" node (under the 
"color" tab bottom left), and then clicking on the "curves" tab near the bottom 
right of the screen.  The crash occurs in graphics/x11drv/dib.c in 
X11DRV_DIB_Convert_888_to_0888_asis().  As a workaround, if I add code at the 
beginning of that function to return if srclinebytes  < 0, then everything works 
fine.
