Package: context
Version: 2009.11.26-2
Severity: normal

Hi!

I use ConTeXt to make my presentations. With the latest upgrade, I am
unable to use linear shades, a concept I borrowed from the ConTeXt
Garden Wiki.

Rather than describe the situation, I attach the sample file I use
(test.tex). test.log is the output when I run it with the latest
ConTeXt, while test_old_context.log is the output when run with
Debian ConTeXt 2008.05.21-1 on a Lenny machine.

The expected output is:
http://people.debian.org/~akumar/dump/test_expected.pdf (made with
Debian ConTeXt 2008.05.21-1)

The output I get with the latest ConTeXt is:
http://people.debian.org/~akumar/dump/test_actual.pdf

I think you can spot the problem here; if I comment out the
\setupbackgrounds line, the outputs look identical.

Please let me know if the error is on my side, and if I need to make
some changes at my end. I believe I've done the "read the changelog"
drill, but I am unable to figure out where the error could me.

Thanks for any advice. I'll be glad to give you further inputs if you
want.

Thanks.

Kumar

Closing this bug.

shell_esacpe_commands have been completely disabled and only
very few really safe programs will be allowed after packaging TL2011.

If you want to make this change and are aware that you might run
a security risk, simply edit the config file in /etc/texmf/texmf.d
to reenable it and add metafon there.

It will not happen due to security reasons.
