Hi,

I just have a case of git cherry-pick dieing with a core dump.
The directly offending lines are get_message() in buildin/revert.c:

	if ((out->reencoded_message = reencode_string(raw_message,
					git_commit_encoding, encoding)))
		out->message = out->reencoded_message;

	abbrev = find_unique_abbrev(commit->object.sha1, DEFAULT_ABBREV);
	abbrev_len = strlen(abbrev);

	/* Find beginning and end of commit subject. */
	p = out->message;
	while (*p && (*p != '\n' || p[1] != '\n'))

and out->message is null at that point.

It looks like reencode_string is returning NULL,
and get_message can't quite cope with that.

This is in v1.7.1 (plus a few mods in git-daemon.c).

I suppose it is a failing of iconv_open, as this is
on sparc SunOS 5.9, but the reaction is a bit harsh.

Unfortunately the debugger is giving me strange
results, like:

434             if (!in_encoding)
(gdb) next
436             conv = iconv_open(out_encoding, in_encoding);
(gdb) print conv
$3 = 0x1003f8
(gdb) next
437             if (conv == (iconv_t) -1)
(gdb) print conv
$4 = 0x1003f8
(gdb) step
474     }

and the disasembly is just as counter-intuitive (with the branch targets).
