Package: grub-common
Version: 1.96+20090709-1
Severity: normal
I'm seeing what I think is a new manifestation of the same bug. On an
earlier version of grub2, I saw the same FPE, then I upgraded and it was
working (sorry, not sure what version that was), and then I (think) I
upgraded again, and now it's crashing, but with a segfault instead of an
FPE.
Backtrace of the crash and other hopefully useful information:
$ sudo gdb ./grub-probe
