Bug 276770

Application: showfoto (1.2.0)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5-amd64 x86_64
Distribution: Debian GNU/Linux 6.0.2 (squeeze)

-- Information about the crash:
I've open a panorama picture through digiKam in showFoto. The picture is of type tiff an has a size of 409 MiB (429 136 546). Its dimensions are 48 344 x 3 877 (187,43 Mpx).

The picture is opened by showFoto without a problem. But when I try to change it zoom factor showFoto crashes.

The crash can be reproduced every time.

 -- Backtrace:
Application: showFoto (showfoto), signal: Segmentation fault
