Getting "'Preload additional info' has encountered a problem. when opening a file in PyDev

Question

Eclipse Platform: Version: 2024-06 (4.32) Build id: I20240601-0610

PyDev for Eclipse 12.2.0.202409031913

wxPython 4.2.2

wxFormBuilder Version 4.2.1-0-g80c4cb6

#######

When I open a file in eclipse using PyDev, I get this error dialog:

Problem Occurred

'Preload additional info' has encountered a problem.

An internal error occurred during "Preload additional info".

Details: An internal error occurred during "Preload additional info". For input string: "11(1)"

######################################################## Sometimes I use PSPad to edit files, and the string "1:1(1)"appears on the status bar representing line 1 column 1.

If I click OK, everything worked fine as far as editing is concerned.

But when I try to execute the program, the bindings between the GUI events and the event handlers in the Python code are scrambled. The wrong handler is called.

Here is the error log entry for "An internal error occurred during: "Preload additional info"."

1. Is this an eclipse problem, pydev problem, wxpython problem, etc?
2. From which file(s) does 'additional info' come?
3. How can I fix this?
