Missing exception log data when using pyinstaller

I’m using loguru in one of my projects while using pyinstaller to create an EXE to run it on several Windows machines. I noticed some log data missing from exceptions when running the EXE. Here is an example of what I’m seeing.

# test.py

from loguru import logger

logger.add('test.log')

def div(n, d):
    try:
        return n / d
    except Exception as e:
        logger.exception(e)

div(2, 0)

When running this from the terminal it will produce this log file as expected.

2020-04-20 12:46:32.123 | ERROR    | __main__:div:9 - division by zero
Traceback (most recent call last):

  File "test.py", line 11, in <module>
    div(2, 0)
    └ <function div at 0x7f81f5ee43b0>

> File "test.py", line 7, in div
    return n / d
           │   └ 0
           └ 2

ZeroDivisionError: division by zero

But once you use pyinstaller (pyinstaller test.py -F) and run the resulting EXE this is what is in the log file.

2020-04-20 12:45:19.427 | ERROR    | __main__:div:9 - division by zero
Traceback (most recent call last):

  File "test.py", line 11, in <module>

> File "test.py", line 7, in div

ZeroDivisionError: division by zero

I have been able to reproduce this with python 3.8 on Windows 10 and python 3.7 on Fedora 30 using loguru==0.4.1 & PyInstaller==3.6

Not sure if this is an pyinstaller issue or a loguru issue, trying here first.
