529781 - Dragging attachment from Sent message truncates the file when using PGP to encrypt

Status: RESOLVED WORKSFORME

(Thunderbird :: General, defect)

Description

[Ben Bourdillon]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.4pre) Gecko/20090915 Lightning/1.0pre Thunderbird/3.0b4

If you send an attachment to someone, using PGP, they can successfully drag the attachment out of the message into an explorer window. However, if you go to your Sent folder and look at the message and try and drag the attachment out, it will be truncated (a 10K file dropped to 2 K). The workaround is to double click on the attachment and then save it - this works fine with no truncation.

If you don't use PGP, there is no problem

Reproducible: Always

Steps to Reproduce:
1. Create a text file of approx 10 Kbytes
2. Create a new message to someone for whom you have a PGP key and enable encryption, signing and PGP/Mime
3. Attach the text file to this message
4. Send the message
5. Verify that the recipent can drag the text file onto their desktop and that the size of the file is unchanged
6. Verify that if you drag the text file onto your desktop from the message in the Sent folder, the size of the file is reduced
7. Verify that if you double click on the text file in the message and save it, the size of the file is unchanged
8. Repeat to the same recipient, this time deactivating signature, encryption and PGP/Mime
9. Verify that the problem has disappeared
Actual Results:  
Steps to reproduce contains the detail

Expected Results:  
Steps to reproduce contains the detail

The dragging of the file to the desktop from the Sent message should not have reduced the size of the file

Here same that WFM (with latest TB build and last enigmail 1.0 (20091119-0602)).

Ben could attach here an email example using above "Add an attachment" link?

Could before try with latest enigmail relase at

When I try to install the latest enigmail, I get:

Enigmail 1.0pre could not be installed because it is not compatible with Thunderbird 3.0b4.

I've added two attachments. Don't know how much use they will be, since the encrypted one is ... well .... encrypted!

Ben

Enigmail 1.0pre works with Thunderbird 1.0 release candidates and recent trunk builds only.

I don't see any relationship to Enigmail here (even if it may look like). Once Enigmail has decrypted a PGP/MIME message it returns the decrypted stream back to Thunderbird, which does with it whatever it's up to. Enigmail is not involved if you save an attachment or drag & drop it to somewhere. 

You might also want to try some S/MIME encrypted message; I'd assume you should obtain the same results.

We recently fixed a drag and dop issue where we had dataloss . I don't have the bug number handy, but it was fixed after b4. can you try in the to be announced rc1 : http://ftp.mozilla.org/pub/mozilla.org/thunderbird/nightly/3.0rc1-candidates/build2/ ?

The RC1 crashes most of the time when I try to send the message ... however the one time that it did not crash, it appeared to truncate the message as before.

the crash is due to enigmail not being to date you'll need to have RC1 + enigmail nightly sorry I should have told you.

I had installed the latest enigmail ....!

but for RC1 you need to have Enigmail 1.0pre, the old version will crash indeed.

Comment 15

[Ben Bourdillon]

That's what I thought I had said!

To make it clear, I installed the latest RC1, then I removed the Enigmail 0.97b (20091105-0557), then I added the latest Enigmail 1.0pre.

I started getting crashes, so I have now reinstalled Thunderbird 3.0b4 and Enigmail 0.97b.

I've spent rather more time on this that I had expected ... so I need to get back to the paying job! (That's *not* to say that I don't really appreciate what you guys are doing. Keep up the good work)

That's weird. Could you tell me the crash ID? I'd like to see what's going on since I don't expect crashes with Enigmail 1.0pre ...

Comment 17

[Ben Bourdillon]

Sorry, I didn't note it down.

As I said, I've now uninstalled the RC1 and Enigmail 1.0pre - thinking about it, the crash may have been the fact that I also had the Contacts Sidebar 0.8 alpha installed ...
