Image plugin priority problems

Hi,

I am having trouble again with the Softimage PIC image format. This time 
with files that have a lot of ASCII text in the header (some of our 
programs write this kind of files). Gwenview recognizes them as 
text/plain files instead of PIC files readable by our kimg_pic.so plugin.

It also happens that if I rename the "test.pic" file to "test.png" 
(without transcoding it), then Gwenview recognizes it just right as a 
PIC file and displays it without problems.

Is there any option to give higher priority to our plugin than the 
text/plain one?

Just in the case it helps, I have all these files in the system to 
support Softimage PIC:

/usr/lib64/kde4/plugins/imageformats/kimg_pic.so
/usr/share/kde4/services/qimageioplugins/pic.desktop
/usr/share/mime/image/x-pic.xml
/usr/share/mime/packages/image-x-pic.xml

Thanks.
