           Summary: showfoto crashes when selecting a filter
           Product: showfoto
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: digikam-devel kde org
        ReportedBy: cnodes gmail com


Version:           0.4.0 (using KDE KDE 3.5.5)
Installed from:    Gentoo Packages
Compiler:          i686-pc-linux-gnu-gcc (GCC) 4.1.1 (Gentoo 4.1.1) 
OS:                Linux

Selecting a filter from the filter menu makes showfoto crash. One filter (I haven't tried every filter) which doesn't result in a crash is 'Distortion Effects ...', but it shows a preview window with no preview.

In digikam everything works fine.

I did a compile with --enable-debug=full configured and a run in gdb resulted in:

I hope this makes sense.
