And all of a sudden, TWINE don't want to start (on LINUX)

Hello there !
My computer is under Linux Mint (64bits). I decided to try Twine, and I had fun.
When I decided to close the program, it didn't work. So, after lots of tries, I did a "top / killall Twine". It worked (of course).
And I could re-launch Twine later. Great.
And now, I can't start Twine at all. Through command line, it says :
"[5553:5554:0313/185310:ERROR:channel.cc(507)] Invalid message size: 527475992
Instruction non permise"
I tried trashing my cache (.cache/Twine) and the Story files in Documents, but nothing changed...
Anyone ?
