[Pkg-phototools-devel] Bug#726370: gphoto2: Nikon D300, Darktable hangs and Dolphin shows error code 150.

[Antoine Beaupré]

Package: gphoto2
Version: 2.4.14-1
Followup-For: Bug #726370

Control: tags -1 - moreinfo
Control: found -1 2.5.3.1-1
Control: affects -1 libgphoto2-6

The problem is not actually with the gphoto2 binary package, but with
the library, which is what darktable really uses.

Case in point: i purged gphoto2 and darktable still starts (but I can
reproduce the hang).

So yes, the problem is still there in 2.5. I see this in my syslog:

Notice how this is not a Nikon D300 but a Canon G12, so I suspect the
problem is not only related with a single machine.

Furthermore, this was working fine in Debian Wheezy, so I am not sure
at all the problem is in gphoto 2.4, if anything it's in 2.5 or
darktable...

Let me know if I test this in any other way.
