Description of problem:
When trying to view a specific HTML message in Gnus, Emacs receives an X error and aborts.
> X protocol error: BadLength (poly request too large or internal Xlib length error) on protocol request 138
Version-Release number of selected component (if applicable):
> $ rpm -q emacs
Seems to be 100% reproducable for me with this specific email.
It was also reproducible with "emacs -q" after loading only my gnus configuration.
Steps to Reproduce:
1. Browse to message in gnus
2. Press enter to view
That I could see the selected message.
Tried to run emacs through gdb, got this backtrace.

Just for claritys sake: "emacs -nw" does not crash.
I've received a second mail which also crashes Emacs, but this time from viewing the subject in the summary view, rather than when opening the mail in the article view.
This is the subject line from the second mail. It includes a three uncommon Unicode characters: REGIONAL INDICATOR SYMBOL LETTER S, REGIONAL INDICATOR SYMBOL LETTER E and a SOCCER BALL.
> Subject: =?utf-8?B?SGVqYSBTdmVyaWdlISBNYXQgdGlsbCBtYXRjaGVuIGbDtnIgZW5k?=
The first mail also included the same SOCCER BALL character, but also a GRINNING FACE character, apart from all the other text. I've tried reproducing the problem by sending myself a mail with these characters but I have not been successful so far.
FWIW, this does not seem to be a regression in emacs 26.
I did the dnf downgrade dance and found that emacs-25.3-5.fc28.x86_64 also crashes.
I imagine this is a duplicate of bug 1519038 .
See upstream report https://debbugs.gnu.org/30874 .

Was that not fixed in emacs 26.1?

Apparently not - I noticed the rpm changelog entry mentioning 1519038 but I could still reproduce the problems mentioned on the upstream bug report with this command:
> emacs -Q --eval="(switch-to-buffer \"*scratch*\")" --eval="(insert-char #x274c)" --eval="(set-fontset-font \"fontset-default\" 'unicode \"Dejavu Sans Mono\")"
I can verify that applying the upstream fix to the emacs-26.1.fc28 package solves the problem. (after cutting away the etc/NEWS change that did not apply cleanly).
Ok, my bad, I should have checked that the patch made it into the stable branch. Sorry about the breakage.
emacs-26.1-3.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-25555f4fe7
The emacs-26.1-3 package works great for me. Thanks Jan!
