PaX MPROTECT killes wkhtmltopdf

[markoran4]

I installed wkhtmltopdf debian package for Wheezy. But when tried to see if the app is working, it was killed by PaX. Is this normal?

Output in syslog is:

it looks like wkhtmltopdf generates code at runtime so it's not compatible with MPROTECT, you'll have to disable it on the binary.
