[Debian-on-mobile-maintainers] Bug#1049433: confy: Displays blank page because of invalid image file (e.g. for CCCamp)

[Benedikt Wildenhain]

Package: confy
Version: 0.6.5-1
Severity: normal

Dear Maintainer,

I viewed the schedule of CCCamp once, which worked, but after is had
been cached, it could not be viewed again, but clicking on the event
afterwards only leads to a blank page and the following output on the
console:

Conference maps links: [{'title': 'Map', 'url': 
'https://map.events.ccc.de/camp/2023/map/'}]

The file in question is a HTML page, so there is probably something
wrong in the schedule information, but that should be handled more
gracefully.

What I did do to fix this problem:

1. Tried to compile the current upstream of confy, which failed due to
outdated blueprint-compiler in debian (0.6).
2. Updated blueprint-compiler to 0.10 (by combining current upstream 
source and
Debian's blueprint-compiler_0.6.0-1.debian.tar.xz)
3. Compiled confy from current git commit 
ebcd379cf64ff78b0637a2755098e8f38c761493 and using 
confy_0.6.5-1.debian.tar.xz

Kind regards
Benedikt Wildenhain
