           Summary: digiKam crashes when other applications rename files
                    it is loading.
           Product: digikam
           Version: 1.4.0
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: kde-bugs at trust.idiom.com


Application: digikam (1.4.0)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-22-generic x86_64

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

I wasn't using digiKam.   However, digiKam was open to a directory in which I
had just placed some photos (with mv).  It crashed as I renamed a bunch of
photos in that directory (with perl).

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
