Problem building pidgin (talkatu)

[Ralph Hyre (edu edition)]

I've not seen 400 errors before, but it seems that the attempt to build
talkatu - as part of a pidgin source build, is causing one.

What's the run-time dependency trying to be resolved here?

All I had to do so far, was install gtk3 and the meson build environment.
