           Summary: Crash when GPS altitude is negative
           Product: digikam
           Version: 0.9.3
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: pave o2 pl


Version:           0.9.3 (using KDE 3.5.9)
Installed from:    Unlisted Binary Package

When a negative altitude is assigned to a photo in the correlation process, that photo's exif data becomes corrupted and causes digikam to crash when displaying it. The workaround is to search for photos with negative altitude before clicking 'apply' in the correlator window, and manually change the altitude to some positive value.

I'm filing this as digikam bug because I'm not sure whether it's the plugin's fault when writing metadata or digikam's when displaying it.
