We need a GDB backtrace to hack. Please run digiKam in GDB like explained here
:

There isn't debug symbols in the Arch's binaries.
Backtrace is very short:

(gdb) bt
#0  0x00000000007b9263 in ?? ()
#1  0x00000000007b97c2 in ?? ()
#2  0x00000000007ab05c in ?? ()
#3  0x00000000007ad6c6 in ?? ()
#4  0x00007ffff26e7d8f in ?? () from /usr/lib/libQtCore.so.4
#5  0x00007fffef652dd2 in start_thread () from /usr/lib/libpthread.so.0
#6  0x00007ffff1912cdd in clone () from /usr/lib/libc.so.6

If it can help you, I can attach catchsegv output - without debug symbols too.

Note: digiKam opens a camera with empty flash without crash, and with one
picture - too. Crashed with three or more pictures in the camera.

Unfortunately:
"Arch

Arch currently doesn't offer debug packages with symbols. You therefore need to
recompile all concerned packages with debugging symbols."
There is nothing to install, and I don't have any desire to recompile
something.

I also observe a crash (segfault) upon trying to download picture from a Canon
S95 camera.

Does not appear to be a Gphoto2 problems as Camera is detected correctly by
Gphoto2 from terminal commandline.

Import was tricky with 2.8. already but crash is new for 3.3.

Greetings,

Georg

If you can still make it crash, could you please get the values of local
variables by doing the following inside gdb:
> f 0
> info locals

Hmm, doesn't give enough information. Can you try info args? And perhaps even
"print info" or "print info.name" when inside the local. And same for
d->status->context to see what really crashes it.

Btw, that size value looks quite big there, but I don't really know how it's
being encoded or so...

Ah, not a problem. So the same thing as before, so first "f 0" and then the
following commands:
> info args
> print info
> print info.name
> print d->status
> print d->status->context

Thanks in advance.

OK.
1. There is four RAW images in a camera.
2. Digikam is running in the gdb.
3. Camera is ON.
4. Say to digikam to import images.
5. Camera window is open and program is segfault:
Program received signal SIGSEGV, Segmentation fault.

--- Comment #17 from Gilles Caulier <[hidden email]> ---
The status handle given by Gphoto library is null. it's abnormal.

Sound like a test case about status is missing to prevent crash, but it sound
like a gphoto2 problem...

More investigation are needs...

Git commit 097f59ea4ba185c55c12c27203c868b006a611f3 by Teemu Rytilahti.
Committed on 07/12/2013 at 19:47.
Pushed by rytilahti into branch 'master'.

Simplify gphoto2 interface by using a shared gpcontext wherever it's possible,
fixes hopefully #322652 as a side-effect.
FIXED-IN: 4.0.0
