SIGSEGV with QT6 on command line export if shell-escape

Thu Sep 21 01:19:31 UTC 2023

For the ctests, we put the following into preferences:

  \converter "pdflatex" "pdf2" "pdflatex -shell-escape $$i" "latex=pdflatex,hyperref-driver=pdftex"

If I export on the GUI, I get a reasonable warning. But if I export on
the command-line something goes wrong with Qt6, but not Qt5 for some
reason. Presumably the issue is that LyX tries to give the warning but
there's no GUI since it's a command-line export.

Attached is the backtrace.

Can anyone reproduce with Qt6? To reproduce, put the above \coverter
command in the user directory preferences file, then do a command line
export (e.g., "-e pdf2 <file.lyx>").
