Considering this issue resolved, invalid due to user configuration problems.

By chance I discovered that QT_PLUGIN_PATH wasn't set, and the issue was resolved by setting it.

export QT_PLUGIN_PATH=~/.kde/lib/kde4/plugins/:/usr/lib/kde4/plugins/

I got some assistance in trying to debug this issue on IRC by mtmx, who states that "[I] do not have a qterminal thread running for some reason, either did not start or aborted and this does not tell us why" by looking at output from running `gdb` and "thread apply all bt".

Actually, if I type "1+1" in the "Command Window" and then press Enter, the command is shown in the "Command History" and the result in the "Workspace". The "Command Window" prompt is just perpetually blinking, still.

I'm running Debian "Jessie" (8) and have 3.8 installed as well as having built 80e630b37ba1 just now. Neither "Command Window" tab is responding - it's just blank. The "Editor" and "Documentation" seem to work just fine. Both versions work in CLI (all I ran was "1+1").

I removed ~/.config/octave to see if there could be something in there that caused this, but I still have the same issue.

What happens when starting octave without gui, i.e


octave --no-gui

Most probably Octave is waiting for something that it has no (more?) access to.

Do you have the option "Allow Octave to connect to the Octave web site ..." (in Network tab in Preferences) set?
(though I wonder if this would cause long delays)

Or does the directory where Octave should start (Octave startup under General tab in Preferences) still exist?

Or perhaps Octave has no access to files it is supposed to access (maybe referenced in .octaverc).

My bet it is something along these lines.

bug #44174
First work good for several months, but fails the command window, blanked.
I have uninstalled and reinstalled.
When I use root after de reinstall the problem appears, but with Control+C was solved.
When I start with my other username I can't solve the blank command window.
OS: ubuntu 14.04
