Bug in konqueror as file manager

Hi,

I use Trinity under Centos 5.7 at work and Ubuntu 11.10 at home.

I noticed some problems with konqueror in file management profile:

1) Both on Ubuntu and Centos, when I click on System icon sidebar I get this message:

Cannot find parent item $( kxdglauncher --getpath --xdgname DOCUMENTS ) in the tree. Internal error.

2) On Ubuntu only some menu items are missing: - menu "Go" is missing - menu "Window" is missing - "Open terminal" is missing in menu "Tools"

I wonder if these are bugs or trouble in my configurations. By the way, is it possible to submit bugs in bugs tracker system ?
