Program terminated with signal SIGSEGV, Segmentation fault.

Thread 1 (Thread 0x7fc5d4482740 (LWP 2701)):
#0  0x0000000000493916 in nxagentDisconnectPicture (p0=0x19b1250,

         x1 = 48234557
         p2 = 0x7fff92ebd2d4
         p0 = 0x19b1250
         pPicture = 0x19b1250
         pBool = 0x7fff92ebd2d4

Looks like we may need a check if nxagentPicture(pPicture) is null.
