[GNC] Gnucash 4.8: doesn't read or store config

[BrianHsu]

Hi,

I've encountered the issue that after install GnuCash 4.8, it won't
read or store my preferences, as described at:

https://bugs.gnucash.org/show_bug.cgi?id=798330

But there is a little different, since I just do a fresh OS install,
I'm sure I don't have any other GnuCash version or XDG_DATA_DIRS
issue.

And I also noticed some strange things, IIRC, after a fresh GnuCash is
installed and launched for first time, it should have the following
behavior:

1. Display a splash screen
2. Show a dialog that contains tips
3. When create a new file, it should have a account setting wizard popped up.

None of above happens when I launch my fresh installed GnuCash 4.8,
which is really strange.

Also, it appears even if I manually ticked those checkbox in
Preference dialog, it just won't save and will not display splash /
tips dialog anyway.

Here is my screen recording to demonstrate this problem:

I've also checked settings mentioned at the bug ticket, but with no
luck. Everything seems correct on my system, but it just won't save my
preference.

I've attached a detail reproduce / investigation steps on the ticket,
hope someone might figure out what happened and help me resolved this
issue.
