[Digikam-devel] [Bug 176873] New: Database synchronisation segfaulted, albums disappeared

           Summary: Database synchronisation segfaulted, albums disappeared
           Product: digikam
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel at kde.org
        ReportedBy: greve at fsfe.org


Version:           2:0.10.0~beta2-1 (using KDE 4.1.3)
OS:                Linux
Installed from:    Debian testing/unstable Packages

I have a fairly large number of pictures, which I had begun cataloging with
digikam. At some point I wanted to make sure that changes were not lost and
selected "Synchronise images with database" at which point digikam segfaulted.

After a restart, digikam no longer shows any albums in the album selection
although in the settings dialogue it still lists the correct path as root for
the collection.

Update, rescan & co have no effect: No albums, no pictures.

When trying another "Synchronise images with database" I get occasional
segfaults - the dump of which is attached below.

I'd hate to lose all the tagging that was done, so I'll stop fiddling now. If
you need more information, please let me know.

Application: digiKam (digikam), signal SIGSEGV
