#852 2.4.10 parentobject is 0xf21280ad, but not in card mode?
System: Up to date Ubuntu 10.04 LTS (Lucid Lynx)
Kernel: 2.6.32-24-generic-pae
Camera: Canon PowerShot S50 (PTP mode)
Remote capture commands:
1) /usr/local/bin/gphoto2 --set-config capture=on --set-config capturetarget=0 --set-config imagesize=2 --set-config iso=4 --set-co
nfig --set-config zoom=5"
2) /usr/local/bin/gphoto2 --capture-image-and-download --force-overwrite --filename=webcam.jpg
Description of problem:
There is no memory card in the camera. An image is taken directly to the camera memory and downloaded via "-capture-image-and-download"
After many successful remote captures, I am getting the following error:
Actual results:
ERROR: Could not get image.
parentobject is 0xf21280ad, but not in card mode?
*** Error ***
lg?
^
Unexpected character 'l'.
ERROR: Could not get image.
gphoto doesn't return a failure error code and instead report success (i.e. 0).
Expected results:
An image is captured successfully. If an error condition is in fact produced, gphoto2 should return a failure code (anything other than zero).
Is there a way to recover from this error gracefully? I tried to set capture=off/on again but that didn't help...
Is there a way to avoid this error in the first place? I specifically took the memory card out completely as without out it overall capture seemed to be more reliable.
Please see attached debug log
Thanks!

Made an interesting observation which seems to suggest what is happening:
1. A corrupted image has been saved to the Camera's RAM:
#gphoto2 -L:
There is no file in folder '/'.
There is 1 file in folder '/store_80000001'.
#1 lgñ rd 150 KB application/x-unknown
2. However, if I try to delete the "rouge" image I get:
# gphoto2 -f /store_80000001 -d 1
Deleting 'lgñ' from folder '/store_80000001'...
*** Error ***
PTP Store Read Only
*** Error (-1: 'Unspecified error') ***
Other variations of the delete operation fails as well...
I am sure rebooting the Camera will solve the issue (temporarily), but I wonder what can be done to avoid it in the first place or how it may be recovered gracefully. I forgot to mention before hand that with the memory card in, i got a lot of PTP timeout issues which is why I eventually took it out completely.
Seems to be in camera memory corruption, as it is still there after libgphoto2/gphoto2 exits.
i am not sure what we can do here :/
