  Ah, I had seen that, but given the date on it and my assumption that
the problem was specifically caused by the most recent changes I figured
that was something else.

  OK, first confirming things do work with 3.5.2-5:

15:38:39 1$ aptitude show eclipse
Package: eclipse                         
New: yes
State: installed
Automatically installed: no
Version: 3.5.2-5

which shows on Help > About Eclipse SDK:

	Version: 3.5.2
	Build id: M20100211-1343

  And then doing this (straight after the upgrade, I didn't try plain
'eclipse' first), the problem is there again.

  That appears to have worked.  Although note his followup, you want
#130, not #135 for the regex that works.  I assume it's expected that an
'eclipse -clean' followed by the sed will cause Eclipse to open with no
Perspectives or Views open?  Simple enough to re-open the Java Browsing
Perspective, if a little annoying.

  I went through the whole thing again, saving my bundles.info at each
stage to have (I sed'd the inter-directory slashes with dashes then
appended a tag):

  So the whole thing does indeed seem to hinge on those
org.apache.lucene(.analysis) lines needing both 'version' strings
updating.  In this case one character per line.
