Consider the following description list, from the rst docs.  Place the
cursor on the line containing "Definition 1.". Press  any number
of times; the only indentation offered is at the beginning of the
line, which breaks the syntax of the list.

term 1
Definition 1. 

term 2
Definition 2, paragraph 1.

Definition 2, paragraph 2.

[Python-modules-team] Bug#886400: python3-pyqt5.qtwebengine: segfaults on simple test

[David Bremner]

Package: python3-pyqt5.qtwebengine
Version: 5.9.2+dfsg-1
Severity: important

-BEGIN PGP SIGNED MESSAGE-
Hash: SHA256

I encountered this when trying to run webmacs (a browser written in
python) on Debian.

The attached script segfaults, seemingly on any URL. Feel free to
adjust the severity up or down; I'm guessing the package works for
some people / applications, but this seems like pretty core
functionality to be broken.

try again with more symbols.
