This issue has to do with VirtualBox-ose the part that runs on the host.
I was experiencing intermittent issues were some executeables were not found
(on the host)
I traced the issue to /usr/local/lib/virtualbox/VBox.sh
VBox.sh hard-codes: PATH="/usr/bin:/bin:/usr/sbin:/sbin"
and launches: /usr/local/lib/virtualbox/VirtualBox
According to FreeBSD audit trails, VirtualBox launches: 'kdeinit4 Running...'
(/usr/local/bin/kdeinit4) inheriting that PATH.
Since that is the second 'kdeinit4 Running...' (and not exclusive to VirtualBox) running on my system I was experiencing some executables working OK where some would not be found.
It is not clear to me why VirtualBox is launching this second copy of
'kdeinit4 Running...' but I might suggest either getting VirtualBox to use it
for its exclusive purposes or to establish the PATH more consistent with what everything else uses.
The most obvious missing part of that PATH is '/usr/local/sbin:/usr/local/bin'
It would seem best to inherit a PATH rather than hard-code it.
I have done some testing with just committing out that hard-coded PATH
and it seems to work better.

I have seen on the web that several others have noticed some 'odd' interference between VirtualBox and other applications. I believe this bug report may shed some light on this interference.
