[Qemu-trivial] black qemu screen on launch

Here is my environment:

1- qemu 1.7.1
2- MacOSX 10.9.4
3- glib & friends 2.40.0
4- configure statement as copied from config.status:
exec './configure' '--enable-cocoa' '--target-list=arm-softmmu' '--disable-vnc' '--enable-debug'
5- The kernel image and rootfs are built via yocto-project (standard, out of the box, no custom bitbake recipes or anything)
6- the command line arguments passed to the executable are:
-kernel /Users/myhome/Projects/QEMU/FinalQEMUBuild/qemuarm/zImage--3.10.17-qemuarm.bin -M versatilepb -hda /Users/maat/Projects/QEMU/FinalQEMUBuild/qemuarm/core-image-minimal-qemuarm.rootfs.ext3 -no-reboot -show-cursor -usb -usbdevice wacom-tablet --append "root=/dev/sda rw console=ttyAMAO console=tty ip= mem=128M highres=off"

====> Results:
- a cocoa window shows up entirely white with absolutely nothing showing...
- when i refresh it (minimize, then show), it turns entirely black
- when i gdb-attach to the process, this is the stack trace:

The configure script picked the sigaltstack as the  coroutine backend.  (I would love to switch it away from sigaltstack, and onto gthread, but I read enough to suggest that qemu is not stable with gthread... so i went with the defaults, for the time being).
What am i doing wrong?

I would appreciate some pointers.
