Synctex behaves inconsistently

[macbuse]

With jupyter lab on ChromeBook/Ubuntu Xenial via crouton/crouton extension.

https://github.com/dnschneid/crouton/wiki/crouton-in-a-Chromium-OS-window-(xiwi)

Details of full config below.

-----------------Behavior--------------------

.tex compiles correctly and is displayed in preview

synctex fails (see trace below) when jupyter lab is executed in a different directory from the .tex source file.

synctex works correctly when jupyter lab is executed in the same directory as the .tex.

-----------------Config ---------------------

python 3.6.6

Jupyter Lab Version 0.34.7 installed via pip install jupyterlab-latex

Ubuntu Xenial 16.04.5 Linux localhost 3.18.0-18121-g8c0cb17dd7e0 #1 SMP PREEMPT Wed Aug 29 14:14:24 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux

@macbuse, thanks for the report! I just published v0.4.1 of the python package, which may have fixed this issue. Can you check if it has?

Works perfectly now. Thanks very useful.

This was the really the only thing left that I needed to switch from my MacBook to the Chromebook..
