558280 - Attempting to paste a portion of the message from the cut buffer cuts the whole buffer

Status: UNCONFIRMED

(Thunderbird :: Message Compose Window, defect)

Description

[Eliot Lear]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

Selecting a portion of text and then attempting to paste over it leads to the entire buffer being placed in the cut buffer.  Undo undoes, fortunately. 

Reproducible: Sometimes

Steps to Reproduce:
1. Select a portion of the text - in the example I will upload, it will be the quoted text as follows:
   The purpose of the
   token is to make it unnecessary for the resource owner to share its
   credentials with the client.  Unlike the resource owner credentials,
   tokens can be issued with a restricted scope and limited lifetime,
   and revoked independently.

2. Copy and Paste the text to the bottom of the message.
Actual Results:  
Entire buffer is cleared

Expected Results:  
Text should have been pasted at the bottom of the message.

This seems to be reproduceable on this specific message for me.   I wonder whether this is at all related to Bug 250539.  I will upload the specific example in a moment.

Attachment: example draft message that causes the problem.

This is the example I mentioned.

I don't fully understand the description ("buffer is cleared"???), but I have observed disturbing copy&paste behavior for a months/years (pasting makes text disappear) in Thunderbird nightlies on Windows 7. If that's this bug, it's dataloss, and I hope it receives a high priority/urgency.

Can you attach an example email in .eml format please ?

Did you try in Thunderbird's -safe-mode ?

Comment 5

[Eliot Lear]

With respect to Comment 4, yes I did.  With respect to Comment 3, will try now.

Sorry- with respect to Comment 3, it was a new message.  I was able to reproduce the error just by copying the quoted text and attempting to past it at the bottom of the message.  Poof.  Entire message gone.
