Comment:

 After some debugging I found out that the issue is not directly in read,
 it is in sugar-base. There is some symlinking happening which we do not
 scope for and we pass an uri to the mime function. I was lucky, that it
 was already fixed upstream (thanks to Aleksey and Sascha), will make it
 available in the 0.84 branch.
