Hi, I tried to replicate the bug, and ran an amd64 unstable schroot build in a loop 10 times.
I didn't get any segfaults, though I did get this warning.
signon-ui_0.17+15.10.20150810-2_amd64.build-libEGL warning: DRI2: failed to
open swrast (search paths /usr/lib/x86_64-linux-gnu/dri:
${ORIGIN}/dri:/usr/lib/dri)
Is it still failing for you? and/or what packages did you have installed
