\documentclass[12pt,demo]{report} 
\usepackage{geometry}    
\usepackage[finnish]{babel}

\begin{document}

Fig. 1 Output is wrong with the geometry package where first line passes the margin, Fig. 2 Output is correct without geometry package

Without geometry the word is not at the edge of the text, so you don't notice that it cannot be hyphenated. — samcarter_is_at_topanswers.xyz, Oct 21 '16 at 17:32

You're missing \usepackage[T1]{fontenc} that makes precomposed accented characters available. Without it, TeX builds the accents and is unable to hyphenate past them.

\documentclass[12pt]{report} 
\usepackage{geometry}
\usepackage[T1]{fontenc}
\usepackage[finnish]{babel}
