Created attachment 170030 [details] the backtrace
I fixed this by removing the older version from slot :2 (i.e. 0.8-r1). It seems you can't have both installed at the same time.
Using the 1.x versions works for qt4. Eventho the bug still seems open upstream, I think it is fixed now.
Yes, reopen if it's still a problem.
