            Bug ID: 350931
           Summary: digikam 4.4.0 suddenly stops searching for new entries
           Product: digikam
           Version: 4.4.0
          Platform: Gentoo Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: NOR
         Component: Import
          Assignee: [hidden email]
          Reporter: [hidden email]

When I start digikam it usually starts searching for new entries. Some day it
started but stopped after a short time of searching. It just stops after e.g.
13% of searching and crashes. Chrashes means, it is still there but no longer
usable.

What I did so far:
System update
digikam reinstall
searched the web --> nothing
used gdb (see below)


Reproducible: Always

Steps to Reproduce:
I simply reproduce ist like this:
1. I put all new pictures (CR2) in specific subdirectories on an external HDD
2. start digikam
3. digikam starts searching for new entries
4. after a while ist just stops. With existing database after 91%. With new
database after 13%. So actually on different places in the db and different
pictures.

Actual Results:  
digikam just stops and hangs somehow. If I stop the process i am not able to
access any album and I do not see any thumbnails.

Expected Results:  
Import all pictures into the db.

--- Comment #1 from Gilles Caulier <[hidden email]> ---
Crash is in Exiv2 shared library when JPEG image is parsed. Please report this
problem to Exiv2 bugzilla with full GDB backtrace and image file relevant when
you read image with Exiv2 CLI tool.
