220381 - Messages in Junk folder are not properly deleted

Status: RESOLVED DUPLICATE of bug 200138

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Gregor Lingl]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de-AT; rv:1.4) Gecko/20030624

WHEN there are at least 2 messages in my junk folder
AND I use Menu-entry Tools/Delete messages marked as junk
THEN all those messages vanish from the folder except one, which
is *now* displayed in the message pane. (I'm afraid that this might activate
certain viruses contained in the junk mail)
MOREOVER only one message less than were originally in the junk-folder
are transferred to the trash folder

Reproducible: Always

Steps to Reproduce:
1. Wait until at least two messages are iput automatically (by the spam filter)
or manually into the junk folder. Chose the junk folder. Don't click any
spammail there. Messages-pane probably contains some mail you have read before
or is empty.
2. Press Tools/Delete mail in this folder marked as junk
3. Observe the counts of mails in junk and trash respectively
4. Observe what appears in the messages pane - namely one of the junkmails 

Actual Results:  
1.The mail-count in the trash folder is one less than was the mail-count in the
junk folder before deleting them
2. A (arbitrary) junkmail isw displayed in the message-pane

Expected Results:  
1. Not display any junkmail in order not to risk giving feedback to the sender
2. count deleted mails (i.e. mails transferred to trash) correctly

Sometimes Using Tools/Delete mails marked as junk leads
to an unrecoverable failure and mozilla crashes.
Not reproducible, seems to depend on the content of some junk-mails???

MAYBE this is also a security problem if those junkmails are infected.
I fear this could be the case, but I don't know exactly.

Actual Result #2 is bug 200138, or possibly bug 89394.  Actual Result #1 looks
similar to bug 162342.

"Sometimes Using Tools/Delete mails marked as junk leads to an unrecoverable
failure and mozilla crashes. Not reproducible, seems to depend on the content of
some junk-mails???"
--That's a separate bug, which should be documented as completely as possible on
its own.

Leaving for someone else to figure how to mark this bug.

Then again, I guess I'll mark it.  Reporter, if you're still experiencing the
unrecoverable error and crash, please fill out a complete bug report on only
that issue (after searching for duplicates, of course).
