reportbug's GUI can be a bit buggy; I suggest using the text interface
instead if it crashes for you (sed -i 's/ui gtk2/ui text/g'
~/.reportbugrc).

I suggest trying out upstream's suggestions in [1], i.e. adding
"rcutree.rcu_idle_gp_delay=1" to your grub command line and/or using a
more up-to-date kernel from jessie-backports.
