anaconda traceback

Description of problem:
I have installed a dual-boot system with Windows 8 and Fedora 23 Alpha, in UEFI mode. When I boot F23 Alpha Workstation netinst and select "Rescue system", I end up in a tmux console with anaconda traceback. The error is in fsminsize.py:57 and the error is:

> UnboundLocalError: local variable 'e' referenced before assignment

The error is not logged anywhere, and no anaconda-tb file is created, so there seems to be a second bug or an omission in logging and crash handling. As a punishment, all you get is a camera shot, because I don't know how else to get the info.

This problem seems to be specific to my disk contents. I have tried the same with a clean F23 Alpha install, and that seems to work. So this is likely related to the dual boot setup.

In the log I see some output related to NTFS partitions:

14:59:34,187 INFO program: Running... ntfsinfo -m /dev/sda4
14:59:34,198 INFO program: stdout:

I tried booting into Windows twice in a row, that didn't help. Maybe it would help if I forced filesystem check from windows. But anyway, anaconda should not crash, even if this was something that could not be fixed from Linux.

Version-Release number of selected component (if applicable):
F23 Alpha
anaconda 23.17-1

How reproducible:
always for my particular disk layout

Steps to Reproduce:
1. install Windows 8 and Fedora 23 Alpha in dual-boot, UEFI mode
2. boot F23 Alpha Workstation netinst (UEFI or BIOS mode)
3. see crash immediately on start
