Segfault in conflict resolver for binary files

Hi,

It seems that we introduced a bug in the interactive conflict resolver
in 1.8 (and later) that is a regression vs. 1.7. It segfaults on a NULL
pointer for conflicts in binary files.

From what I could find out is that for binary files, the conflict resolver
description doesn't actually set the IS_BINARY flag but that doesn't
seem to be the core problem. Rather, the conflict skel does not provide
a path for the local modification and the MY_ABSPATH element in
the descriptor remains NULL and causes the segfault.

The attached script demonstrates the problem and the .patch file
provided a workaround that is not a proper fix. Select either "df" or
"m" at the 'resolve' prompt.
