Package: zathura
Version: 2026.07.02-3
Severity: important

Dear Maintainer,

zathura in testing and unstable seems to suffer some linking issues, crashing
before startup with message:

zathura: symbol lookup error: /usr/lib/x86_64-linux-gnu/libgtk-4.so.1: undefined symbol: gst_play_config_set_loop

I tested versions 2026.07.02-1 and 2026.07.02-3 .

This looks to me vaguely similar to a situation with gajim in #1130014 , but I
was unable to fix this by applying the same dependency change. Might be the
case that this is actually a problem of libgtk-4-1, but I found I don't have
other gtk4 apps to bisect.

In case some debug information is needed to solve this, please let me know.
