user7561: I installed electrum a while back and noted down the 12 word seed. Haven't used it for a few months, but now when I go to view my seed (clicking on the seed icon on the bottom right of the GUI), it asks for my password, and then the dialogue says: 
"Your wallet generation seed is:"
And the text box below is completely empty, underneath which it says:
"Please write down or memorize these 0 words (order is important)..."
A bit concerned my seed seems to have vanished. Any suggestions?

user7561: Answering my own question: appears I have uncovered a bug in electrum. The password I was entering was incorrect: the last 2 characters were wrong. However if I entered a completely wrong password I did get an "incorrect password" error, and the seed dialogue did not open. 
Discovered by virtue of the command line console which did report incorrect password error when I entered the first wrong-by-two characters password. 

user15558: it is most likely this bug, fixed now:
