Hey jamie721 did you ever find a solution?

Did anybody get a solution to this? I am getting the exact same error also writing a game. Worked fine until upgrade. Works fine in the simulator. Or does anybody know how this can be traced to cause?

Dump of assembler code for function _ZNK14QGraphicsScene9focusItemEv:
0x41aa837c <+0>: push {r4, r5, r11, lr}
0x41aa8380 <+4>: add r11, sp, #12
0x41aa8384 <+8>: ldr r4, [r0, #4]
0x41aa8388 <+12>: bl 0x41aa8054 <_ZNK14QGraphicsScene8isActiveEv>
0x41aa838c <+16>: cmp r0, #0
0x41aa8390 <+20>: ldrne r0, [r4, #184] ; 0xb8

0x41aa8398 <+28>: pop {r4, r5, r11, pc}
End of assembler dump.
