Thanks for this hint. It was missing in the makedist script. I have fixed this
and a 2.4.1-1 tarball is underway.

Actually, the lines above are the real problem:

MidCOM appearantly tries to load the root node but NAP determines that it is
hidden due to ViewerGroups (line 1). MidCOM then tries to traverse upwards to
find a visible node (lines 2 and 3). Since the root node is invisible, this
fails and is not correctly treated at that point (this is the bug), as it does
detect that the node -1 is not accessible, but won't treat it correctly as it
just continues running instead of triggering an access denied error.

See this bug: http://midcom.tigris.org/issues/show_bug.cgi?id=248

2.4.1-1 should fix this too in that it now shows an error message in these cases.


Live long and Prosper!
