Cripes I just tried installing 7zip and squishee and after fixing a quote mis-match on line 88 I got this (on my N800 OS2008):

/home/user # squishee.py
process 1754: D-Bus library appears to be incorrectly set up; failed to read machine uuid: Failed to open "/var/lib/dbus/machine-id": No such file or directory
See the manual page for dbus-uuidgen to correct this issue.
D-Bus not built with -rdynamic so unable to print a backtrace
Aborted
