I was able to reproduce it today a few times, until i was not... :-)

Switched tab, edited a file, saved, switched tab back and #0 was there.
Did the same. Was there again.
Then i tried the same, just without saving. Was there again.
And then tried both of the above but it did not happen again :-).

But yes, it seems to be something with switching the tabs.
