Confirming.

This seems to affect multiple (all?) GTK apps like Meld (doesn't start) and
Geany (just exits after one chooses "File Open")

Problem seems to be that the apps cannot find the schemas dir. One can work
around it by setting GSETTINGS_SCHEMA_DIR env. variable.

Like when you extract the app in /tmp it works like so:

GSETTINGS_SCHEMA_DIR="z:\tmp\windows_czkawka_gui\share\glib-2.0\schemas" wine
czkawka_gui.exe

I don't know if this variable is set on windows by the app, or if this path is
somewhere set in the registry by the app? Rafal, any ideas?

--- Comment #2 from Louis Lenders  ---
Did some more testing, maybe the troubles is caused by the XDG_DATA_DIRS
environment variable.

This is on my Antix distro set to /usr/local/share/:/usr/share/

But I think the apps get confused by it as they seem to use it as well.
I can start the applications like

XDG_DATA_DIRS=""   wine czkawka_gui.exe and then they run . I think wine might
need to unset this variable?

Unsetting XDG_DATA_DIRS also allows Meld to start properly, and "fixes" the
crash in Geany after "File Open" is clicked.

So this seems to be the culprit here. Somehow wine needs to unset this
variable.
