Comment 8 for bug 1059559

The only way that I was able to reproduce this error is by taking a reference manual folder and removing the reference manual marker, so I'm betting someone did that in Oxfam and then corrected it, which is why the error stopped appearing.

In any case, I changed the intranet layout to just ignore the navigation if it doesn't exist, so no error will be thrown anymore, even if this is not exactly what happened.

Deployed to cguardia-1059559-oxfam-error, but note that this is a general karl bug, so it's fixed in the karl package (that is, the oxfam package is not needed to test this).
