So you you think stash_group_add_string is buggy
This was my first guess but it seems wrong.
In #3151 the commit [be739e2](https://github.com/geany/geany/commit/be739e28a6e29aeb08912af36620a4fb78b311...) was identified as first buggy commit, but that doesn't change stash_group_add_string as far as I can tell.
Yeah, be739e2 is more relevant and the patch in #3151 fixes reading the VTE settings for me.
