It took me a long time to figure out the same problem (but with a
different command). Well, my cron job that wouldn't work was a
monthly job and so I pretty much had to wait until the next month to
test any changes.
The key is this snippet from crontab(5) :
The sixth field (the rest of the line) specifies the command to be
run. The entire command portion of the line, up to a newline or %
character, will be executed by /bin/sh or by the shell specified in the
SHELL variable of the crontab file. Percentsigns (%) in the command,
unless escaped with backslash (\), will be changed into newline charac
ters, and all data after the first % will be sent to the command as
standard input.
Change all '%' in your command to '\%'.
