System Information
Operating system: Linux-5.3.0-29-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 660M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 430.50

Blender Version
Broken: version: 2.83 (sub 1), branch: master, commit date: 2020-01-29 10:19, hash: 3ee219b845
Broken: version: 2.81

Short description of error
Blender crashes when opening a file from the user preferences or render window, and an error popup is displayed in the main window.

Exact steps for others to reproduce the error

From --factory-startup
Open User Preferences
Call Open… (Ctrl O)
In the filebrowser, select a non-existing file ending with .blend
Press Enter to confirm (do not click the Open button)
- An error message appears: Cannot read file '/test.blend': No such file or directory
Without moving the cursor, so that the error popup is still displayed, call Open… again
- Blender crashes.

Upon crash there are — sometimes — two Python tracebacks:

Traceback (most recent call last):
  File "/home/damien/blender-git/build_linux/bin/2.83/scripts/startup/bl_ui/space_filebrowser.py", line 306, in poll
    return context.space_data.params.use_library_browsing and panel_poll_is_upper_region(context.region)
AttributeError: 'NoneType' object has no attribute 'params'

location: <unknown location>:-1

location: <unknown location>:-1

and the following, which appears several times:

Traceback (most recent call last):
  File "/home/damien/blender-git/build_linux/bin/2.83/scripts/startup/bl_ui/space_filebrowser.py", line 282, in poll
    return not context.preferences.filepaths.hide_recent_locations and panel_poll_is_upper_region(context.region)
  File "/home/damien/blender-git/build_linux/bin/2.83/scripts/startup/bl_ui/space_filebrowser.py", line 161, in panel_poll_is_upper_region
    return region.alignment in {'LEFT', 'RIGHT'}
AttributeError: 'NoneType' object has no attribute 'alignment'

By "immediatly afterwards" you mean while the error popup is still open? Then yes, I can reproduce it, otherwise not.
I do not get the python errors, but maybe that is because Blender crashes earlier for me.

Yes, that seems to be the case. Updating description.

I tried again, and the Python errors don’t happen each time. I couldn’t tell in which case they do, though.

Based on @JacquesLucke’s answer, this crash actually seems to happen when any error popup is displayed.
For instance:

Open User Preferences
In main window, open a text editor and execute some invalid Python code
Switch to the preferences window without moving the mouse (e.g. Alt + Tab)
Open…
- Don’t Save
Crash
