Segfault when format_out leads to empty out #107

Closed nheir closed 8 years ago

nheir commented 8 years ago

Step to reproduce: package-query -Qs firefox -f "%t" or package-query -Qs firefox -f ""

That issue is rare but it's a segfault after all.

It comes from util.c, string_t.s is NULL as long as there is nothing to add (including empty string). Then pkg_to_str return NULL instead of empty string and print_package doesn't handle it.

@nheir Thanks for the report! I'll get it handled.
