Earlier today, Desora put up a video of Sagat guardbreaking Ryu with his Ultra. A couple hours later, I came up with a couple of setups that apply to Seth. Here’s Henaki’s video of the glitch:

You can find more information about the glitch itself in the main SF4 forum. What I’m going to do here is list a couple of setups that work, as well as any possible ways for the cast to escape.
Note: The glitch appears not to work when the opponent quickstands no matter how perfect your timing is.
Setup 1: midscreen backthrow, Strong Sonic Boom, wait a bit, Ultra.
Setup 2: midscreen Legs BNB combo, Jab Sonic Boom, confirm that the opponent didn’t quickstand, Ultra.
Setup 3: midscreen SPD, wait a bit, Jab Sonic Boom, Ultra.
I’m sure there are corner variations of these two setups.
Now for character-specific escapes:
Fei - Roundhouse Chicken (Seth can bait this and do the ultra later.)
Cammy - EX Knuckle (Seth is safe, can probably punish.)
Akuma - DP+KKK teleport (Akuma can possibly super or ultra demon after.)
Gouken - counter (Seth is safe.), EX Demon Flip (Seth is NOT safe.)
Dhalsim - teleport
Blanka - EX Rainbow (Seth might not be able to block.), command backhop (eats the boom in midair)
Chun-Li - EX Hazanshu (Seth is safe.), backdash (eats the boom in midair)
Ryu - EX DP (Seth can punish.), backdash (eats the boom in midair)
Honda - backdash (eats the boom in midair)
Zangief - backdash (eats the boom in midair)
Guile - He’s screwed!
Ken - Strong DP (Seth is safe, can maybe punish Ken.)
Seth - Ultra (Both Seths whiff.), teleport
Bison - EX Headstomp, EX Devil Reverse, backdash (eats the boom in midair)
Sagat - He’s screwed!
Balrog - backdash (eats the boom in midair), EX Rush XX Ultra (HITS SETH FULLY, EASY TO DO.)
Vega - backflip (Seth can bait this and do the ultra later.)
Abel - EX Roll (Can likely punish Seth after the roll.) (Abel’s kara Ultra still loses to Seth’s Ultra.)
Viper - backdash (eats the boom in midair)
Rufus - EX Snake Strike (Seth is safe, can probably punish Rufus.)
Fuerte - backdash (eats the boom in midair), EX Guac (can possibly RSF after starting with Run)
Sakura - She’s screwed!
Rose - backdash (eats the boom in midair)
Dan - EX DP (Seth is safe, maybe Seth can punish)
Gen - EX Oga (Seth eats a free Ultra.)
