error: PKGBUILD contains CRLF characters and cannot be executed

When trying to install some (though not all) packages from AUR using yay or pacaur, such as rstudio-desktop or zotero, I get the following errors (translated from German):

:: checking integrity of zotero...
==> ERROR: PKGBUILD contains CRLF characters and cannot be executed.
:: preparing zotero...
==> ERROR: PKGBUILD contains CRLF characters and cannot be executed.
:: failed to verify integrity or prepare zotero package
:: failed to verify integrity or prepare zotero package

This is right after a new install and update of Manjaro. It did not occur after another new install yesterday. I can confirm that in ~/.cache/pacaur/ and ~/.cache/yay/ there are PKGBUILDs with CRLF, which also return if I delete them and retry.
