Bug#806177: general protection ip:7f1572272b8c sp:7ffe1d1f0ef0 error:0 in libcairo.so.2.11400.4[7f157223b000+10e000] crashes gnome-shell

[Yaroslav Halchenko]

Package: libcairo2
Version: 1.14.4-1
Severity: important
File: /usr/lib/x86_64-linux-gnu/libcairo.so.2.11400.4

I was in a preview mode (super) and closed one of the windows inthere (forgot
which one ;) ) which lead to the restart of the gnome-shell (on the next
restart I think gnome will announce that unrecoverable error, and would
cause to log me out). journalctl gives following limited details

sorry -- know that not much of detail... but there is no even libcairo2-dbg, so
not sure what else information I could harvest even if attach in gdb to
gnome-shell to monitor for future possible similar cases.
