פירוש על עבודה זרה 33:11

This is a different version of the above material. The midrash had said that one who repents of minut dies. But if one repents of another sin, one does not die? But didn’t R. Hisda say to the woman who came to repent of incest that she was going to die? And in this version she does die.
The answer is that since she said this was her lightest sin, we can presume that she also performed acts of minut from which she was also repenting. The woman died because of minut, not because of incest.
