[xdebug-general] xdebug.trace_format Does Not Change cachegrind.out.nnnn Format

I installed xdebug 2.1.3 on a CentOS 5 system running PHP 5.2.13 and
Apache 2.2.3. I updated php.ini with the following, appended
XDEBUG_PROFILE=1 to a Drupal URL and was able to get a function trace.

zend_extension=/usr/lib64/php/modules/xdebug.so
xdebug.profiler_enable_trigger = 0
xdebug.profiler_output_dir = "/tmp"

I then set xdebug.profiler_enable_trigger = 1, add the following lines and
restarted Apache. However, the format of the output file looks identical
to what I had before. Setting xdebug.profiler_enable_trigger = 2 made no
difference. I verified that the values are being picked up using
phpinfo(),

xdebug.collect_params = 4
xdebug.collect_return = 1

Am I missing something obvious?
     Thanks, Norbert
