As you may have guess, I found a mimetype problem for any trinity 
applications.

I just found out that k3b for trinity cannot open/recognize its own saved 
projest files/mimetypes (just like chalk doesn't). However k3b for kde4 could 
and that was the clue. 

Install chalk and try to open a template. Or create and save a project with 
k3b for trinity. See if they work.  I don't think it will. I'm not jumping to 
the conclusion that I'm right. However I have seen this across 29 machines so 
far.

The reason, I think, for that is because these mimetypes are for kde4 (best 
way I can explain it). I can open k3b saved projects in k3b for kde4, but not 
in k3b for trinity. The mimetype designs for kde3 / 4 are not compatible with 
r14. These appears randomly throughout the gui, for example kword cannot open 
an rtf anymore etc etc.

As I dig deeper I'm finding more of this. I can do work arounds but they're 
ugly and not sustainable.

These problems only relate to trinity and does not affect gtk or others.

Please let know what all of find.

When I have time I'll try to file a bug report.

Thanks
