flyback does not run as crontab or in ssh shell: error: could not find python module gtk

[GoogleCodeExporter]

What steps will reproduce the problem?
1. python /usr/local/flyback/flyback.py --backup 
2. works when run in gui window, does not work in cron or on a remote ssh shell
3. message: error: could not find python module gtk

What is the expected output? What do you see instead?
expected: run the backup. instead: error message

What version of the product are you using? On what operating system?
flyback 0.4.0, python 2.5, gtk2.0, fedora core 8

Please provide any additional information below.
It looks like the command line version unnecessarily tries to call the gui
which is not available in a cron shell or a ssh shell. I recommend to
remove all gui dependencies in case flyback is invoked non-interactively.

I see exactly the same issue in Fedora 10. I've no experience with programming
python. Are the modules loaded prior to the parsing of the command line 
--backup arg?

I solved this by installing xvfb which is essentially a /dev/null Xwindow and  
prefixing the crontab entry with xvfb-run

My crontab entry now reads

0 3 * * * xvfb-run python /opt/flyback/flyback.py --backup
