Bug#1001090: latex-beamer: backport bugfix for bibliographies to Bullseye

[Nils König]

Package: texlive-latex-recommended
Version: 2020.20210202-3
Severity: wishlist

Dear Maintainer,

the version of beamer shipped in Bullseye's texlive-latex-recommended contains a
bug preventing beamer files with multiple \printbibliography calls from being
processed successfully. This can happen if e.g. the bibliography is split in
literature sources for the content and another section for the images used in
the presentation.
The bug was already fixed upstream and modifying my installed files to apply
this patch was successfull in resolving the problem:

https://github.com/josephwright/beamer/commit/a41c6a779ca1f921d536ea9d9a2785ff6d5df615

From the datetags of Bookworm's and Sid's packages I'm assuming they already
include the fix, but imho it would be a very good idea to backport it to
Bullseye too — if my local modification is something to go by it should apply
without conflicts.

A minimal sample failing to be processed in unpatched Bullseye,
but working with the patch, can be found further below.

Cheers,
Nils König

Sorry, we don't do backports. Assuming the fix is only a three liner,
you may put the fixed file into your local texmf tree. I tag the bug a
wontfix, we'll close it upon next release.
