Some precisions:
it is a type 2 or Type 3 error.
I have also a crash (very often, but not always), removing a single line
specially after a previous crash. 
Deleting a dozen of line, i got more than a dozen of crash, a reboot of my machine.

too buggy. My last test. I'll stop here with the download manager.

Trashed the file downloads.rdf
Launch Mozilla
Downloaded  a sit file
Opened the download manager. The display was correct. Only one line
Save as, with "page complete" of a web page
The download manager show now the old line and a blank line a top of the list.
Closed and reopen the download manager. No changes
Quit Mozilla
Lauch Mozilla
Open the download manager.
now, I see  the two lines...

Not tried to delete, it's enough. I'll try with more downloads

Just another thing, on "remove from list" a javascript error is generated.

DUPE of 153480?
Reporter, can you reproduce and submit a Talkback incident?

As i said in the description, i sent two talkbacks, without my email, but the
words "remove from list" appear in the text

Today i Can't reproduce the problem.

Yesterday after sending the talkbacks, and created the attachement of my
downloads.rdf file, i have installed build 2002070908

I have reproduced easily the problem, more than one time. I have not sent
TalkBacks with this build.

Today, with the same build, i can't reproduced the problem(For the Moment)
I have only noticed theese:
- After deleting a line, some times a blank line appears in the list
- After a remove, a new selection is not hightlited (See Bug ID 156489)
- The selected file name (In the bottom in the Window, is not updated correctly
after a delete, it must show the new selected line)
- The "remove from list" tab is enabled, when nothing is selected, (ie after
deleting all)

It seems minor problems, but who nows...

Tell me if you are able to find my talkbacks, otherwise i'll send one as soon as
possible.

I said that i have java scripts errors:

when removing a line:
Error: minValue is not defined
Source File: chrome://communicator/content/downloadmanager/downloadmanager.js
Line: 224

when removing all remaining lines:
Error: [Exception... "Component returned failure code: 0x80070057
(NS_ERROR_ILLEGAL_VALUE) [nsITreeContentView.getItemAtIndex]"  nsresult:
"0x80070057 (NS_ERROR_ILLEGAL_VALUE)"  location: "JS frame ::
chrome://communicator/content/downloadmanager/downloadmanager.js ::
getSelectedItem :: line 254"  data: no]
Source File: chrome://communicator/content/downloadmanager/downloadmanager.js
Line: 254

Attachment: info.db file in my prefs system folder

My talkBack window is empty, i suspect that it is a side effect of the
installation of the new build. I have found this file in my system prefs.It 
contains probably useful information about the two talkbacks i sent about this
problem

I select auto Detect for the type. I hope it will be correct

The "Component returned failure code" JS error makes me think this is a dup of
Bug #132331, but then the "minValue is not defined" JS error is part of Bug #147842.

Anyone else have any thoughts?

Today my dowload managers show me 4 empty lines at the top at the window.
I have delete the first thrre lines easily (Some time i had to click twice)
To delete the last empty, i had to delete the visible lines before

No Crash for the moment

I suspect some corruption of the downloads.rdf file

Attachment: An downloads.rdf file that is supposed to be empty

I don't know the format of a downloads.rdf file, but after deleting all the
lines
it's contents seems curious

According to doron / timeless @ #mozillazine the stack goes something like..

<@doron> 0x00000008
<@doron> nsDownloadManager::RemoveDownload() [nsDownloadManager.cpp, line 666]
<@doron> CODE.10
<@doron> XPTC_InvokeByIndex() [xptcinvoke_mac.cpp, line 145]
<@doron> XPCWrappedNative::CallMethod() [xpcwrappednative.cpp, line 1993]
<@doron> XPC_WN_CallMethod() [xpcwrappednativejsops.cpp, line 1266]
<@doron> js_Invoke() [jsinterp.c, line 788]
<@doron> js_Interpret() [jsinterp.c, line 2743]

which is the same as bug 153480, as far as I can tell.
reopen if I'm wrong.
