I just added this bug:
http://bugs.activestate.com/show_bug.cgi?id=81497
This *only* affects people running Komodo 5.1 nightly builds that use the remotedrivetree extension, and only seemingly for recent builds. The simplest way to avoid this bug is just to use 5.0.3 instead ( that's what I'm doing for now ).
I just wanted to post this notice now because Todd maintains both that extension, and the remote files code, and he is currently away for a month in Australia and Fiji. =)
