Running downloaded Fether manually
$ /home/xx/.config/Electron/parity --light --chain kovan --ws-interface 127.0.0.1 --ws-port 8546
Segmentation fault
$ ls -lh /home/xx/.config/Electron/parity
-rwxr-xr-x 1 xx xx 252K Jul 13 16:38 /home/xx/.config/Electron/parity
252K... I guess the download failed?
Removing /home/xx/.config/Electron/parity
and relaunching Fether (making it download Parity again) fixes the problem
