After an update to php5-common this night, cron reports a sed error invalid option -- 'z'.This problem has also been reported on the Debian mailing list.What should I do, until the problem is resolved through another update, to fix this issue in the meantime?I fear that messing with the cron entry, that the package created, I could cause the next update to fail.
Cron reports error in php5-common job after update

As @artfulrobot pointed out in his comment, 5.4.35-0+deb7u2 was released, which fixes the issue. After installing it, everything went back to normal.
