gtk problem after update

After an update of debian testing several days ago some applications crash. Its clearly a gtk error.

for example mousepad:

(mousepad:4203): Gtk-WARNING **: 10:33:25.001: Could not load a pixbuf from icon theme.
This may indicate that pixbuf loaders or the mime database could not be found.
**
Gtk:ERROR:../../../../gtk/gtkiconhelper.c:494:ensure_surface_for_gicon: assertion failed (error == NULL): Failed to load /home/jods/.local/share/icons/Papirus-Dark/16x16/actions/image-missing.svg: Error opening file /home/jods/.local/share/icons/Papirus-Dark/16x16/actions/image-missing.svg: No such file or directory (g-io-error-quark, 1)
[1] 4203 abort mousepad

I googled reinstalled some applications, tried some stuff but nothing seems to work.
