[Bug 279996] New: Crash while running face detection

https://bugs.kde.org/show_bug.cgi?id=279996

           Summary: Crash while running face detection
           Product: digikam
           Version: 2.1.0
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: Face Detection
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:           2.1.0 (using KDE 4.7.0)
OS:                Linux

Running face detection results in a crash nearly every time. Tested with
current git at b52126a820bbaabe7e63a7da4a6f404af48ff07e

I found some similar bug reports, but all closed "fixed".



Reproducible: Sometimes

Steps to Reproduce:
Press "Scan collection for faces" and "Start"

Actual Results:  
At some point digikam crashes with a pure virtual function call.

Crash at /home/rikky/sourcecode/digikam/libs/threadimageio/loadingcache.cpp:247

it.value()->notifyNewLoadingProcess(process, description);


Expected Results:  
Face detection should not crash

QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in
use, all queries will cease to work.

There were indeed similar bugs, and they were fixed (people could reproduce the
crash, and after applying a patch it did no longer crash).

Now you have these crashes again, and not many other people. Is there anything
special? Does it crash when scanning a specific image? The filenames are
usually printed on the console. Are empty files involved, or files which cannot
be loaded?

Ping?

If possible, try with current git to ensure you have all fixes applied.

Enrico,

Can you reproduce the crash using digiKam 2.4 ?

New crash information added by DrKonqi

digikam (2.1.1) on KDE Platform 4.7.4 (4.7.4) using Qt 4.7.4

- What I was doing when the application crashed:

Started digikam from console: got message
QSqlDatabasePrivate::removeDatabase: connection 'ConnectionTest' is still in
use, all queries will cease to work.
(I always get this when starting digikam)
scanned for faces on large collection of images (probably about 2-3000)
At some point (seems to be different each time) dk crashes with

pure virtual method called
terminate called without an active exception
KCrash: Application 'digikam' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/john/.kde/socket-nova/kdeinit4__0
No itemShortInfo could be retrieved from the database for image
"20060730_165211_img_8422.jpg"

I had this crash symptom occurring on a different collection of images and
after several runs it eventually processed the collection without crashing.
(And I re-ran the scan on the same collection to be more sure that it wasn't a
fluke.)
