           Summary: showfoto crashes when enlarging an image
           Product: showfoto
           Version: 0.2.0
          Platform: SuSE RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: angelo sns it


Version:           0.2.0 (using KDE KDE 3.4.2)
Installed from:    SuSE RPMs
Compiler:          SuSE 10.0 RPM 
OS:                Linux

I selected 15 photos. In enlarging the 6th (650x434 pixels), showfoto crashed 2 times in succession. I had a lot of programs (and a dozen or more of Konqueror tabs) opened at the same time. 
I've tried to reproduce the crash later, but (luckly) showfoto seems stable.

**The backtrace is:
