kamoso will not open ,png after upgrade

What happens when you try?

Kamoso, red bar, unable to open (image/PNG) not supported

If you make a new user, is it ok there?

on the 11.04 Kamoso, and viewing pictures, the document viewer used to open pictures, 12.04 the document viewer no longer opens pictures. you have to scroll down to the (open with) and use the (image viewer,) however in Kamoso this feture is not available, the pictures appear as red blocks at the bottom and you can't do anything with them. Even in 11.04 you had to go through several steps to open and save them, and or move them to another computer. Now I find that the pictures are saved to pictures foulder in the home folder by default, and instead of a red block its posted as a thumbnail. you still have to use the (Open with) feature. Which is several steps quicker than it was before.

so thats it
