How reproducible:
Try starting gnome-terminal either from activities or from console

Steps to Reproduce:
1. Open console
2. start gnome-terminal
OR
1. Click on Activities (upper left corner)
2. Enter 'terminal'
3. Start by clicking on 'Terminal'

Actual results:
nothing appears on the Desktop, not even an error

When started from the console this is the output (gnome is started):
$ gnome-terminal 
# Locale not supported by C library.
#       Using the fallback 'C' locale.
# watch_fast: "/org/gnome/desktop/interface/" (establishing: 0, active: 0)

# watch_established: "/org/gnome/desktop/a11y/" (establishing: 1)
# Error constructing proxy for org.gnome.Terminal:/org/gnome/Terminal/Factory0: Error calling StartServiceByName for org.gnome.Terminal: Timeout was reached


Expected results:
gnome-terminal to show up

Additional info:
happend since upgrade from F27 to F29.

I tried also to reinstall gnome-terminal:
dnf remove gnome-terminal
dnf install gnome-terminal

It didn't change anything.

$ gnome-terminal 
# Locale not supported by C library.

There you have the root problem already. You need to use a UTF-8 locale.

Comment 2 Harald 2018-11-11 16:51:30 UTC

I am using the UTF-8 locale, i have the language set to en_US.UTF-8 but the keyboard and the units set to de_DE.UTF-8. 

But it looks like I was able to identify the rootcause, and it is that the upgrade dropped the german language pack, causing the gnome-terminal to fail the start. The issue of dropped language pack has already an bug filed, as well as gnome-terminal not starting without LC_ALL being set.

With some research I found this issue: 
Bug 1185658 - gnome-terminal won't start without LC_ALL defined 

Now i checked my locale settings:
$ locale
locale: Cannot set LC_ALL to default locale: No such file or directory
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC=de_DE.UTF-8
LC_TIME=de_DE.UTF-8
LC_COLLATE="en_US.UTF-8"
LC_MONETARY=de_DE.UTF-8
LC_MESSAGES="en_US.UTF-8"
LC_PAPER=de_DE.UTF-8
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT=de_DE.UTF-8
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

=> So the missing setting of LC_ALL seems to cause the gnome-terminal not starting. Now I checked for the reason why this happened and I found this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=1574222

A solution is described here, simply install the language pack again:
http://www.hack23.de/blog/2018/05/fedora-28-upgrade-problem-mit-locale-settings/

I run 
dnf install glibc-langpack-de
dnf reinstall gnome-terminal

and now the gnome-terminal is starting as it should (still not from the console, so this might be impossible anyway).
