153952 - Clearing list of already downloaded files causes crash

Status: VERIFIED DUPLICATE of bug 153480

(SeaMonkey :: Download & File Handling, defect)

Description

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1a+) Gecko/20020623
BuildID:    2002062304

There are several talkbalks:  TB7660780K, TB7660762G, TB7658192Q for this
problem.  With this build any attempt to remove the files that are finished
downloading causes a crash.  This may be a duplicate of others, but I don't use
RDF, etc.  The list entry that I am trying to delete is actually the
mozilla-i686-pc-linux-gnu-sea.tar.gz for this build.  It will crash if all I do
is start mozilla, then start download manager, then try to remove from list.

Reproducible: Always
Steps to Reproduce:
1.Start mozilla
2.Remove item from download manager list
3.

Actual Results:  crash

Expected Results:  item removed

I had another idea.  I tried selecting individual files.  I was able to remove
everything except the mozilla download from the this.  I don't know whether the
problem is because it is mozilla or because it is the first on the list.  The
attempt to remove the mozilla download generated another talkback:  TB7663897H

Further information.  I got tired of the crashing so I moved the download.rdf. 
When I looked at it I found two things:
 1) There were multiple entries for this file, with varying numbers of download
dates for each entry.  That may be the cause of the crash.
 2) There were a great many entries.  Why?  I've removed them from the list
according to the download manager.  This will be a privacy concern.  Is this a
residual bug?  Another bug? A feature (if so, it will lead to problems)?

Still more.  I looked at the download.rdf and noticed one thing that is unique
to the name that causes the crash.  It is the only one that has a DownloadState
that is 3.  All the other files have "1".  This one entry has both "1" and "3".

This could also be irrelevant.  There are various other normal looking entries
for the mozilla tar file.  I don't know which one it the one that causes the crash.
