That's normal because Wireshark doesn't provide this popup. Redhat (on which
CentOS is based) makes use of a program called 'consolehelper' to run programs
that (frequently) need to be root to run but they don't want to install
setuid-root (or, in the case of Wireshark which _can't_ be installed setuid
root because Gtk won't let it run).
For example, "/usr/bin/ethereal" (which is usually early in most normal users'
$PATH) is just a symlink to 'consolehelper':
mozart [~/]> ll /usr/bin/ethereal
lrwxrwxrwx 1 root root 13 Apr 27 20:11 /usr/bin/ethereal -> consolehelper*
whereas "/usr/sbin/ethereal" (which is usually early in 'root's $PATH) is the
Real Thing(tm):
mozart [~/]> ll /usr/sbin/ethereal
-rwxr-xr-x 1 root root 1465824 Apr 25 21:38 /usr/sbin/ethereal*

Whatever the problem is, I'm 95% sure it's a problem with 'consolehelper', not
Ethereal/Wireshark.
You could verify this yourself by running "/usr/sbin/ethereal" (or
"/usr/sbin/wireshark") as a normal user and verifying it comes up OK (without
the popup from 'consolehelper', of course).
Actually, reading the 'strace' output you provided, "/usr/bin/ethereal" (aka
'consolehelper') never even got around to forking or exec'ing the real
'ethereal' so now I'm 99.9% sure it's a 'consolehelper' bug. You might want to
report this to Redhat instead.
BTW, I just tried "Run Unprivileged" on RHEL AS3 Update 6 and it worked fine
for me, not sure why, maybe Redhat already fixed it? The changelog for the
'usermode' package doesn't give any hints, though...
