Sorry for my english ;)
segmentation fault
Hello, I cannot change the settings on my canon eos 600d from fedora 16, python 2.7.3, gphoto2 2.4.14
import piggyphoto as pp
C.leave_locked()
C.config.main.imgsettings.iso.value = 3

Add a license
Hi,
I forked your project and am using it for one of mine. In your readme, you encourage usage but you don't have a license. If you could add (an open source) one, that would be really great.
If you're interested I can share my modified version (python3 compatible)
Segmentation Fault on Mountain Lion installed through Macports
I installed Python 2.7, gphoto2 and libgphoto2 through Macports on Mac OS X, and updated the library link within __init__.py to point to the correct file.
However running the snap.py script distributed with piggyphoto now results in a segmentation fault.
I previously installed and configured this same script, based on piggyphoto, successfully on another Mac OS machine. However, since that time two things have changed in the environment I'm working with.
- The version of Gphoto2 within the Macports repositories has rolled forward a full minor version, from 2.4.x to 2.5.x
- The Mac OS X build is now Mountain Lion, whereas I'd previously tested successfully on Snow Leopard and Lion.
I'm strongly suspecting it's the GPhoto2 version change which is the underlying issue. Any idea what changes I can make to piggyphoto for compatibility with Gphoto2, or if I can rebuild/debug the ctypes bindings somehow.
The segmentation fault report is shown below...

memory leak
Hi! I'm having a memory leak when liveview is running, is there any way to avoid this?
Regards
code:
def liveview():
global main_surface
C = piggyphoto.camera()
C.leave_locked()
C.capture_preview('./Ims/preview.jpg')
picture = pygame.image.load("./Ims/preview.jpg")
pygame.display.set_mode(picture.get_size())
main_surface = pygame.display.get_surface()
pygame.display.set_caption("Vista en Vivo")
while not quit_pressed():
C.capture_preview('./Ims/preview.jpg')
show("./Ims/preview.jpg")
pygame.display.quit()
C.exit()
os.remove("./Ims/preview.jpg")

It seems to be incompatible with debian squeeze python2.7 - something has changed in ctypes maybe?
