Problem

The plot_title keyword seems to error for the PGFPlotsX backend, not sure if there is something with my latex installation or something in the PGFPlotsX package, but since it was with a keyword from Plots.jl that it errored on, and the offending tex code seems to be \clip \pgfextra{\pgfplotspathaxisoutline} which can be found in Plots.jl, I felt this might be a place to start at least.

I can reproduce with

using Plots; pgfplotsx()
Plots.pdf(plot(plot_title="hello"), "hello.pdf")
