Bug#354804: krita: TIFF and PNG exports don't work with a CMYK image

[Fabrice Flore-Thebault <fab@centsix.org>]

Package: krita
Version: 1:1.4.90.2-1
Severity: normal

TIFF and PNG export don't work with a CMYK image, at least on ppc. 
The same for ISO Uncoated and Adobe CMYK.
TIFF export is producing something weird like 
http://centsix.org/debian/tmp/tocollant-aldil-cmjn-v1.tiff
PNG export makes an empty file.
Both exports are working great with a RVB image.
