I took a fast look on it. I noticed it seemed to not stop try to triangulate the non quad faces, since after 15min and 3.5GB of memory it hadn't stop to work.
The problem is happening only if we select the entire object of if we try to select (just a highlight) any edge in the bottom circle.
I did a loop cut close to it and removed that area and then I could triangulate without problem.
So, it seems to be a very specific problem. If it cannot be reproduced it doesn't worth spend time looking for a problem ("bug ?!")
