I just checked, all MATE packages are 1.14.0 or 1.14.1; marco is 1.14.2.
This was the case all along since MATE was upgraded from the previous
version in Sid.
The bug did disappear a week ago or so, but it's back as of today. I
really don't understand what causes it, since Marco wasn't updated
However, I must have been quite tired when I initially reported it
because I didn't think of reading ~/.xsession-errors. Indeed, every time
Marco crashes, there are these two error messages:
marco: ../../../../src/cairo-surface.c :953 : cairo_surface_destroy:
l'assertion « (_cairo_atomic_int_get (&(&surface->ref_count)->ref_count)
> 0) » a échoué.
Avertissement du gestionnaire de fenêtres : Log level 16:
g_object_set_valist: object class 'MetaFrames' has no property named 'type'
(in French, "a échoué" means "has failed", and "Avertissement du
gestionnaire de fenêtres" means "Warning from the window manager").
Hope it helps.
