[Bug 295751] New: Segfault while importing from camera with digiKam via gphoto2

https://bugs.kde.org/show_bug.cgi?id=295751

            Bug ID: 295751
          Severity: crash
           Version: 2.5.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: Segfault while importing from camera with digiKam via
                    gphoto2
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Archlinux Packages
            Status: UNCONFIRMED
         Component: Import
           Product: digikam

digiKam segfaults when I try to import images from a Canon IXUS 60 camera via
ghoto2. However, importing with gphoto2 in the console works without problems.

Reproducible: Always

Steps to Reproduce:
1. Import from predefined camera (no images are shown)
2. digiKam segfaults

Expected Results:  
Import pictures from camera


Unfortunately, the gdb backtrace is very short and probably useless:

Starting program: /usr/bin/digikam

Install digikam debug package and run digiKam through gdb to get a full
suitable backtrace to hack.

Ok, I compiled digiKam from source with debug and here's the backtrace. I hope
this helps.
