What do you do in such cases? Make sure you log both: stdout and stderr.

a) sh -c 'your quoted command &> /tmp/logfile'

b) if this still does not work use strace:

sh -c 'strace -f-o /tmp/strace.log your quoted command &> /tmp/logfile'

Then you know how much is happening.

You may also want to check that the environment is the same. Eg export > file to create a file containing your environment. Then source it in the cron job line somehow.

I'm not using cron that often so the solution could be simpler.
