Got a segmentation fault in libtk8.6.so

Python Help
1

I got following segmentation fault when I debug my python code. It seems something wrong in tkinter, but I have no idea what should I do to figure it out. My OS is ubuntu 23.04 and python version is 3.9.19

Thread 1 "python" received signal SIGSEGV, Segmentation fault.

And how do I get my python code traceback when the segmentation fault occur? I suspect thing getting problem when code is preformed in:

        try:
            self.text_box.configure(state=tk.NORMAL,font=("宋体", 12))
            self.text_box.insert(END, str(time.strftime('%I:%M:%S ')) + message+'\n')
            self.last_sent_label(str(time.strftime( "Last message sent: " + '%B %d, %Y' + ' at ' + '%I:%M %p')))
            self.text_box.see(END)
            self.text_box.configure(state=tk.DISABLED)
        except Exception as e:
            raise e

Did I read somewhere that tk has problems with some unicode characters?

Does the code work if you change the font?

4

To be honest, this problem is not appear so frequently, and the input is generated by large language model, so I was unable to get the problem-characters, I’m going to try to log the output of llm, and change that font. If it make any difference I would reply.

You can use LLM to give you ideas about the code, but need to use your human judgment as to the fitness of the code at the moment.

6

There is a misunderstanding, code is written by myself, but I used tkinter to display the out put of llm. And I tied a few of fonts which got from font.families(), unfortunately, the segmentation fault still alive… It may derive from other place.

Thanks for clarification.

Suggest you investigate if the problem is font related but can you use a newer version of python?
3.9 is old and the problem you are seeing may have been fixed in a newer version.

If you cannot upgrade ubuntu or python consider running newer version in a VM.

You could write messages to a log file around where you suspect it might be failing in the Python code, something like:

            with open(log_path, 'a') as file:
                print('Set font of text_box', file=file)
            self.text_box.configure(state=tk.NORMAL,font=("宋体", 12))
            with open(log_path, 'a') as file:
                print('Insert text', file=file)
            self.text_box.insert(END, str(time.strftime('%I:%M:%S ')) + message+'\n')
            with open(log_path, 'a') as file:
                print('Last sent', file=file)
            self.last_sent_label(str(time.strftime( "Last message sent: " + '%B %d, %Y' + ' at ' + '%I:%M %p')))
            with open(log_path, 'a') as file:
                print('See text_box', file=file)
            self.text_box.see(END)
            with open(log_path, 'a') as file:
                print('Disable text_box', file=file)
            self.text_box.configure(state=tk.DISABLED)
            with open(log_path, 'a') as file:
                print('OK', file=file)

I cannot read the crash log, but there have been instances where Ubuntu has fonts (perhaps loaded by user) that appear in the tk font list but which are not compatible with tk’s use of the graphics system. I have no idea ‘whose fault’. This is all I know.

Thanks for your advice, I changed the font from ‘宋体’ to ‘times’, this core dump have been not occurring yet.
