            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: digikam-devel at kde.org
          Reporter: ndbt2014 at gmail.com

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.
