Seems like a "too complex" password generates "gist: unknown error" when trying to "Create Public gist"

I got the error message "gist: unknown error please report a bug" when trying to "Create Public Gist".
The error is displayed after entering
"Gist Descripttion: some deiscription" AND
"Gist File Name: "

The password I used was:
sEvn¤k2#d0sndQe0gj

and when I changed to shorter password with letters and digits and no other characters like %&/
it worked great.

I changed back to the complicated password and it did not work again. I got the same error message.
Maybe something to look into...
