art backend : NSView crashes

[Riccardo Mottola]

Hi,

if I open a new empty window in PRICE, I get a crash when using the art 
backend, but not the cairo one.

Program received signal SIGSEGV, Segmentation fault.
0xb75404a3 in objc_msg_lookup ()
   from /usr/lib/gcc/i686-pc-linux-gnu/4.9.2/libobjc.so.4
(gdb) bt
#0  0xb75404a3 in objc_msg_lookup ()

    at PRWindowController.m:258
#2  0x08286020 in ?? ()
Backtrace stopped: previous frame inner to this frame (corrupt stack?)

it is not very useful I fear.

I suppose that a NSView with an empty image is a problem with the art 
backend
