I had subscribed to
ScrapBook's rss
feed, and a bugfix was just released, bumping the current
version up to
0.15.5.
It fixes a bug where, 'if control characters get mixed in' [into?]
~/.mozilla/firefox/[profilename]/ScrapBook/scrapbook.rdf, 'the
sidebar tree disappears'.
Interesting: I launched Firefox using my 'scrapbook' profile,
launched Firefox again with the -profilemanager option, and went to
update ScrapBook in the 'scrapbook' profile instance, and it
updated successfully. Running the other instance didn't cause the
install to barf. Restarting that instance of Firefox is necessary,
of course.
scrapbook.rdf is an XML document, and it is the sidebar
content.
An aside, because I once was in a Solaris admin class where the
instructor casually asked whether a version 0.42 (or some such
two-digit number) is newer than a version 0.9, and many people got
the answer wrong. The higher the number, the more recent the
version. So, grab the two-digit numbered versions, not v0.9.
