vim error when opening file

[bjoernma]

When I open a python file when "Plugin 'SkyLeach/pudb.vim'" is active in the .vimrc file, I get (translation added by hand) Fehler beim Ausführen (translation: error on execution) von "BufRead Autokommandos für ".py" ..function <SNR>20_SetInitialBreakpoints[26]..BufRead Autokommandos für ".py"..function <SNR>20_SetInitialBreakpoints": Zeile 26: (translation: line 26) Traceback (most recent call last): File "", line 10, in vim.error: Vim(sign):E474: Ungültiges Argument (translated: invalid argument)

The error vanishes directly when commenting out the Plugin in the .vimrc file.

Could it be due to a parallel use of pudb directly in the bash?

I'm currently using Vi IMproved 8.2, last patch 2121, and the standalone pudb v2024.1.3
