Segmentation fault when using Flash Uploader in WP 2.6

My system information:

PHP version = 5.2.6 apache2handler
Webserver = Apache/2.2.9 (FreeBSD)
Database = mysqlt 5.0.51a, lock.system=flock
Operating system =FreeBSD 7.0
gettext = enabled
Locale = en_US
Browser = Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

When creating a post or page, the flash uploader is the default choice when adding media. Take note of the following Apache log entries:

[25/Jul/2008:19:34:25 -0400] “GET /blog/wp-includes/js/swfupload/swfupload.js?ver=2.0.2-20080430

I click on the “Add media: “add an image” icon > (dialog box pops outs) From Computer > Choose Files to Upload (button) > selected an image file > “Crunching” on the progress bar (appears frozen)

The corresponding Apache access_log entry:

[25/Jul/2008:19:35:22 -0400] “POST /blog/wp-admin/admin-ajax.php HTTP/1.1” 200 182

1-2 seconds after, these lines show up (i use “tail -f /var/log/messages /apache/error_log to monitor them in realtime)

==> /var/log/messages <==
Jul 25 19:35:40 web kernel: pid 52607 (httpd), uid 80: exited on signal 11
==> /apache/error_log <==
[Fri Jul 25 19:35:41 2008] [notice] child pid 52607 exit signal Segmentation fault (11)

On that same dialog box, appears You are using the Flash uploader. Problems? Try the Browser uploader instead. > I click on Browser uploader > Browse > selected that same file > clicked on “Upload” > immediately shown the thumbnail and the button to “Save all changes”.

The corresponding Apache access_log entry:

[25/Jul/2008:19:35:43 -0400] “GET /blog/wp-admin/media-upload.php?post_id=-1217028862&type=image&flash=0
[25/Jul/2008:19:35:52 -0400] “POST /blog/wp-admin/media-upload.php?post_id=-1217028862&type=image&flash=0

I was able to reproduce the same set of Segmentation fault errors on a fresh install of 2.6

Any ideas why this is happening? Please advice, thank you.
