           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: digikam-devel at kde.org
        ReportedBy: Enrico_m at gmx.de


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.
