Example TGA file

SUMMARY
When zooming into TGA formatted World of Warcraft screenshots, they become corrupted and extremely bright. With each increment/decrement of the zoom level above 100% the image gets progressively worse and brighter.

I have also found this occurs with some TGA images included in various add-ons (see the uploaded attachment).

STEPS TO REPRODUCE
1. Open the attached "whispervine.tga" image in Gwenview
2. Zoom in beyond 100%

OBSERVED RESULT
The rendered image is broken and very bright

EXPECTED RESULT
The image zooms correctly
