The line 34 of the Quebec Schedule G is not properly calculated. It should be the result of line 30 - line 32 but it is forced to 0. In my case, the line 30 is X and line 32 is empty. So the line 34 should be equal to line 30, but it is not. This removes the capital gain and corrupt the TP1 lines 137-139.

Btw: The capital gains from federal Schedule 3-Supp after June are not transposed to the Quebec Schedule G-Supp after June section (I will file an other bug report). But with that bug, I suspect the line 34 issue will also apply to the line 134 of schedule G.
