Comment 2 for bug 522875

So I get both
Feb 16 21:51:03 ubuntu kernel: [ 5102.344572] ubiquity[10420]: segfault at 7f192c2b6840 ip 00007f19400a1494 sp 00007fff96c34940 error 4 in libglib-2.0.so.0.2303.0[7f1940061000+cd000]
and
Traceback:
 Traceback (most recent call last):
   File "/usr/lib/ubiquity/plugins/ubi-summary.py", line 152, in on_advanced_button_clicked
     self.set_summary_device(self.grub_device_entry.child.get_text())

Apport doesn't produce a backtrace for the glib segfault, that's probably some kind of bug with ubiquity being a python application?
So is this a dupe of #509838? Probably.
