It was:

The first time I got the error like this:
1. Boot a fresh Tails USB install.
2. Don't set sudo password.
3. Start tails-persistence-setup, set a passphrase and press create.
4. Error!
5. Reboot.
6. Set a sudo password.
7. Start tails-persistence-setup, enter password, press create.
8. Success!
I haven't been able to reproduce step 4. I have found another (weird)
way to kinda reliably reproduce it the error, though:
1. Boot a fresh Tails USB install.
2. Run tails-persistence-setup, set a password and press create. It
should work.
3. Reboot.
4. Set a sudo password (needed by GParted below).
5. Use GParted: Remove the TailsData partition, format empty space as
"unallocated" with no label. Apply the changes.
6. Use GParted: Delete the new partition. Apply the changes.
7. Run tails-persistence-setup, set a passphrase and press create.
8. Error!
I ran tails-persistence-setup --verbose, and here's what I got:
Working on device [...]
Running step bootstrap
Entering main Gtk2 loop
Creating partition of size [...]
waiting...
org.freedesktop.UDisks.Error.Inhibited: Daemon is inhibited
After doing the above steps cloning doesn't work either. Here's the log:
Warning! All data [...]
Press 'Next' [...]
Unmounting /dev/sdc
Daemon is inhibited
LiveUSB creation failed!
Daemon is inhibited
Attached is the full log (I ran liveusb-creator -v). Restarting dbus
(and consequently X) fixed it.
Even though the above steps certainly isn't something we want to support
I hope it all can help you identify the original source of the error.
(As a side effect it seems like the above steps (1-8) make Tails on the
USB drive unbootable.)

Sure. I suppose I really wasn't "pretty sure" at all :). It was just a
wild guess based on the fact that it worked as soon as I rebooted and
set a sudo password.

These widgets could be hidden behind an "Advanced settings/install"
button and/or could be automatically shown only when a small enough USB
drive is selected, e.g. <=2 GB (but big enough to fit Tails).

I just fear that we're setting the requirements for Tails too high,
effectively alienating poor people, and unnecessarily preventing fully
adequate devices from being usable with Tails. Speaking for myself, I
got my first >2 GB USB stick just a few months ago.

IMHO, if this is an issue for us when adding a feature we want, then we
may want to reconsider our whole approach, possibly by maintaining a
fork (gasp! :)). I guess my point is that it seems like a poor argument
to say that "we don't want X since X is hard to get upstream" at least
if X is important for us, which may or may not be the case for this
particular X. In this case, however, I'd actually expect this feature to
be a useful for other distros using liveusb-creator, so why not push
something like that upstream? In the future, of course, since we're on
deadlines.
Here's some more, unrelated suggestions:
* In the liveusb-creator, please add the name of the USB drives' models
to the list of USB devices one can install Tails to.
tails-persistence-setup currently lists the name, but IMHO it's more
important for the installer to do so since that's were the real risk of
selecting the wrong device is.
* When persistence has been successfully setup, prompt the user with an
OK-pop-up containing the success message (and OK -> exit application)
instead of changing the window to contain the success message and asking
users to close it themselves. That seems more streamlined to me.
Otherwise, at least add a close/exit button.
Cheers!
