A new stable version of darktable (1.4) has been released: http://www.darktable.org/2013/12/released-darktable-1-4/ Could you please make it available in F19 repo, in updates-testing if not the regular one. Thanks.
I've been already asked to do so. Build process is ongoing. Packages are coming to updates-testing as soon as possible. *** This bug has been marked as a duplicate of bug 1025748 ***
