From 62e3436b5f3461662929eae102beefbd12127cb1 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Wed, 26 May 2010 13:22:26 -0300 Subject: perf tui: Reset use_browser if stdout is not a tty MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The newt initialization routines weren't being called because the output was a file (perf annotate > /tmp/bla) but use_browser was still 1, because ~/.perfconfig had it as 'on', so, later on newt routines segfaulted.
