[Aptitude-devel] Bug#967911: aptitude: aptitude-changelog-parser leaves garbage on the screen

[Sven Joachim]

Package: aptitude
Version: 0.8.13-1+b1
Severity: normal
X-Debbugs-Cc: Sven Joachim <svenjoac at gmx.de>, Guillem Jover <guillem at debian.org>

When viewing the Debian changelog of bash in aptitude's TUI, I saw the
screen flash and then error messages from aptitude-changelog-parser
appeared scattered across the screen, redrawing the screen with Ctrl-l
got rid of these and displayed the changelog properly.

The bash changelog has at least two incorrectly formatted entries for
versions 2.01.1-3.1 and 2.01-0 which aptitude-changelog-parser
apparently complains about.

Viewing the changelog from the commandline with "aptitude changelog
bash" does not show such a problem, though.
