Re: [O] Suspected bug with LaTeX export: the pdf does not open

[Tim Cross]

Given the problem appears to only occur with older setups which are
using an external PDF viewer, he problem might be with the xdg settings
on the system. The line

   Running /usr/bin/xdg-open /home/cochard/tmp/scr.pdf...done

might be worth more investigation. What program is xdg using to open PDF
files? What happens if you try to run that viewer manually on the PDF
file?
