I am trying to export one VM (powered off) as an appliance, and getting 
failure every time.
GUI and running VM both crash with SIGTRAP at the time I press "Export" 
button. See log message from this crashed VM:
<...skipped...>

Another log in home directory shows this:
!!Assertion Failed!!
Expression: progress.isOk()
Location  : 
/usr/ports/emulators/virtualbox-ose/work/VirtualBox-4.2.16/src/VBox/Frontends/VirtualBox/src/globals/UIMessageCenter.cpp(2564) 
void UIMessageCenter::cannotExportAppliance(const CProgress&, 
CAppliance*, QWidget*) const
progress is not okay (RC=0x800706BE)

Another notable thing is that when I restart GUI this crashed machine 
shows there as "Powered off" which is wrong, VBox crashed when it was 
running, this isn't just normal powered off state.
Host is not affected.

vbox-4.2.16_2 on 9.1-STABLE amd64
