Bug#1124759: paraview: ParaView crashes with a segmentation fault when opening the Python Script Editor via the GUI menu.

[Jin Seok Park]

Package: paraview
Version: 5.13.2+dfsg-3
Severity: normal
X-Debbugs-Cc: aeropark at gmail.com

Dear Maintainer,

when using the Debian package of ParaView, the application crashes with a
segmentation fault when opening the Python Script Editor from the GUI.

What led up to the situation:
ParaView was started normally on a Debian system using the packaged binary.

What exactly did you do:
I clicked “Tools → Python Script Editor” from the main menu.

What was the outcome of this action:
ParaView immediately crashed with SIGSEGV (signal 11). A backtrace indicates
the crash occurs in the Python editor components (libpqPython-pv5.13.so.1),
with the first Python-related frame in libpython3.13.so.1.0
(PyObject_GetAttrString).

What outcome did you expect instead:
The Python Script Editor window should open normally without crashing.

The issue is fully reproducible on this system.

A shortened backtrace is shown below:

Caught signal 11 (Segmentation fault: address not mapped to object at address
0x8)
  libpython3.13.so.1.0(PyObject_GetAttrString+0xd)
  libpqPython-
pv5.13.so.1(_ZN25pqPythonSyntaxHighlighterC2EP7QObjectR9QTextEdit+0x2ad)
  libpqPython-pv5.13.so.1(_ZN16pqPythonTextAreaC1EP7QWidget+0x165)
  libpqPython-pv5.13.so.1(_ZN17pqPythonTabWidget17createNewEmptyTabEv+0x4d)
  libpqPython-pv5.13.so.1(_ZN20pqPythonScriptEditorC2EP7QWidget+0xb1)

This may indicate an incompatibility between ParaView 5.13 and Python 3.13 as
packaged on Debian, particularly in the Python Script Editor.

Please let me know if further information or a full backtrace is required.

Regards,
