Summary:	Python files temporarily taken as matlab files

Description David 2020-02-26 17:09:47 UTC

Steps to reproduce:
- Create some valid python (.py) file.
- Edit the file so that it would start with commented lines having 3 (three) "#" symbols.
- Edit some line so that it would contain a decimal number with exponential notation (e.g. 1e1).
- Inspect the folder in which the file is located with Dolphin, without pressing F5.

Expected behavior: should recognize the file as a python file.

Actual behavior: takes the file as a matlab file, until refreshing, after which it becomes a python file, but upon editing it again will become matlab once more, and will again become python upon next refresh.

Example:

import numpy as np

n = int(1e1)
k = int(5e0)
nz = int(.5*n)
lam = 3e0

This is an issue in the shared-mime-info product. Please open a bug at https://gitlab.freedesktop.org/xdg/shared-mime-info/issues.

Thanks!

But the problem doesn't happen when I browse the folder with nemo or nautilus.

Hmm, maybe those apps use a different mechanism? Not sure. Either way, similar recent bugs have always been traced to shared-mime-info, so let's start there.
