If I understand the theory correctly, this is
because the cable is too tight, and you should
turn the barrel in (clockwise) to make it more
slack. This actually worked, but how can it
happen that the cable is too tight suddenly?
Shouldn't it be more loose rather?


Sounds like the cable isn't able to move freely enough. As Frank noted,
a common trouble spot is where it might pass under the bottom bracket
shell. Try lubricating there first, after cleaning it of course. If
that doesn't help, check that where the cable passes through the outer
casing it is lubricated, and that the derailleur mechanism isn't binding
or in need of cleaning and lubricating.
