This is now happening every time I try to start my preferred text editor -- THE, The Hessling Editor -- in a terminal. Never had this problem with any version of Ubuntu, Kubuntu, Mate, Mint, Debian, whatever.

Something even odder: it never worked in Yakuake on SUSE, but it used to work fine in Konsole. Now it never works in either of them (I try it every day). All in openSUSE 13.2.

What's going on, and how can I fix it?

The full message is: THE terminated with signal: 11

Running on AMD64.
