GPhoto driver crashes

GPhoto driver crashes was created by Clément

Hello,

I have noticed that since I updated INDI on my machines (on saturday for the earliest one), the GPhoto driver always crashes when I try to start it. I have tested with both the Nikon D40X and D90 cameras. I've tested it with the following configurations:
  • Raspberry Pi with Raspbian Jessie, INDI updated with today's package
  • The camera directly plugged on a laptop running the latest Ekos VM. INDI was using the saturday build, but I updated it to today's build, and it does the same

Besides, I have tested to take a picture in commandline using gphoto2, and it works, so this issue comes from INDI.

In the INDI logs, it just says
indi_gphoto_ccd: stderr EOF
then
indi_gphoto_ccd: restart #3

And in the indi_gphoto_ccd debug logs, I get the following:

It looks like there is something wrong with the exposure widget?

Hello,

Has anyone been able to reproduce this issue? I still have it, so I cannot use my Nikon cameras on my telescopes for the moment...

The program indeed segfaults, below is the GDB backtrace.
The segfault happens when the program tries to access the attribute format_widget, which is a null pointer; with a breakpoint before the segfault, printing the attribute returns 0x0:
(gdb) print gphoto->format_widget
$3 = (gphoto_widget *) 0x0

I have tested it on Ekos VM, it works now, thank you!

However it looks like the Raspbian packages have not been updated since the 14th July. Are Raspbian builds configured in the Travis CI?

Solved
I have intalled the update tool synaptic and then i have updated also Kstar, other INDI driver and basis packages
Now it work well and Gphoto seem more stable with my EOS 1000D (just a little drouble to do the first preview from Ekos but nothing blocking)
