Description Doug Semler 2009-12-16 22:46:55 UTC

Version:            (using KDE 4.3.4)
OS:                Linux
Installed from:    Unlisted Binary Package

When attempting to load a monochrome TIFF image (dolphin preview, kolourpaint, or any other KDE-base application), a message stating "Unable to load, invalid image format" (or no preview, or similar message) is displayed if the image file is missing the BitsPerSample TIFF tag.  This tag is optional in monochrome images, with a default value of '1'.  Adding the tag with the correct value causes the images to be displayed/load properly.

Downgrading from qt 4.6 to qt 4.5.3 solves the issue.

(NOTE: this is *NOT* an okular bug, okular works, the assignee will need to be changed.)
