            Bug ID: 339909
           Summary: Digikam 4.2.0 Segmentation Fault on open in 14.10
                    Lubuntu
           Product: digikam
           Version: 4.2.0
          Platform: Ubuntu Packages
               URL: https://www.youtube.com/watch?v=i3xORCE6ttc&feature=yo
                    utu.be
                OS: Linux
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: general
          Assignee: [hidden email]
          Reporter: [hidden email]

Hi!   KDE Crash Handler had an error when sending the report, so I will copy
and paste it's information here.  


///////
Application: digikam (4.2.0)
KDE Platform Version: 4.14.1
Qt Version: 4.8.6
Operating System: Linux 3.16.0-22-generic x86_64
Distribution: Ubuntu Utopic Unicorn (development branch)

-- Information about the crash:
- What I was doing when the application crashed:

Digikam consistantly crashes when the "scanning for new files" bar reaches
100%.  I have included a video link to show the behavior.     Please note the
bottom right, where you can see the bar climbing towards 100% before crashing.
The video shows 4 crashes.

https://www.youtube.com/watch?v=i3xORCE6ttc&feature=youtu.be

The only customizations I can think of:   Customizing which file types Digikam
recognizes.  (Added a svg, svgz, xfc, various video formats, and a few other's
which I can not remember.)    In addition, I have ~250,000-400,000+ files in my
library.

I believe this behavior also happened with 4.3.0 while I was on 14.04 (4.2.0
worked fine at that point, from my memory.).   I am unable to test 4.4.3 on
14.10 due to not being able to find a working ppa and not exactly being
technologically inclined to install otherwise.


Unlikely to be helpful clues:

Also, prior to this behavior, I would experience crashing when accessing
certain folders.   (Presumably folders that contained a certain filetype
Digikam was K.O.ing itself from.)   And Prior to this, I was experiencing
crashing when working with tags (either renaming them, adding, deleting them..
Not sure).   Also, I would notice an odd behavior in renaming a folder causing
all of my folders to open which were opened on the last shutdown (I'm
guessing).


Computer Specs:  

OS: Lubuntu 14.10
Processor: I5-3750k.   ...Or whatever the common K series I5 Ivy Bridge number
is.
Ram: 16gbs ddr3
HDD: Root has 2GBs of free space, and the Digikam configuration files database
and thumbnails database drive has 4.5 GBs of free space.  
Graphics: Intel HD 4000

The crash can be reproduced every time.
