Thanks for the response - I am aware of the dangers - my goal is to help catch bugs and contribute to debian.
If you consider these bugs as spurious, is there a better way to upgrade gnome early and still report bugs that are useful? Thanks, Abhijit.

I worked around the problem by holding the package to 3.26.x. I think this is better represented as a libgnome-desktop bug: the new libgnome-desktop from experimental is not yet ready for full-stack testing. When I saw this crash, it was because the same process had both libgnome-desktop-3-12 (via libmutter) and libgnome-desktop-3-17 (via gir1.2-gnomedesktop-3.0) in the same process space, and they fight. gir1.2-gnomedesktop-3.0 (>= 3.27) should probably have a Breaks on libmutter-1-0 (<< 3.27) to prevent the broken situation from being installable. However, Mutter 3.27 has not yet been uploaded to experimental, so if that was done, there is no version that would be co-installable with libgnome-desktop-3-17 yet. ii libc6 2.27-0experimental0 ii libpolkit-gobject-1-0 0.113-6 You appear to be installing all available packages from experimental. This is almost certainly a bad idea. If they were ready for general use, they wouldn't be in experimental. smcv
