The cause of these crashes is that libgphoto2 changed its ABI / API, without changing the library soname. A rebuild of entangle against new API is required to fix the crash.


Based on the stack trace in initial description, there may be a second bug lurking here. Once a build with the crash solved is available, we can see about diagnosing any remaining bug.

entangle-0.5.0-3.fc18 has been submitted as an update for Fedora 18.
https://admin.fedoraproject.org/updates/entangle-0.5.0-3.fc18

I connected a Canon PowerShot G15 camera to the USB port of my computer.

@cristian: can you try the pending update entangle-0.5.0-3.fc18 to see if it improves matters.

It stopped crashing.

Package entangle-0.5.0-3.fc18:
* should fix your issue,
* was pushed to the Fedora 18 testing repository,
* should be available at your local mirror within two days.
Update it with:
# su -c 'yum update --enablerepo=updates-testing entangle-0.5.0-3.fc18'
as soon as you are able to.
Please go to the following url:
https://admin.fedoraproject.org/updates/FEDORA-2013-2911/entangle-0.5.0-3.fc18
then log in and leave karma (feedback).

No more crash; seems to work (testing takes time)

It still crashes with the Kodak EasyShare DX4530. I will try it with the Nikon later.

Installed Packages
entangle.i686                   0.5.0-3.fc18                    @updates-testing

It doesn't crash with a Nikon coolpix 5700 in PTP mode.

I can trigger and capture photos.
I can change the resolution, aperture, shutter speed, focal length, etc.

Some Glib warnings are displayed. (see below)
