Thunderbird freezes when dragging unread encrypted e-mail

[OC]

I run Thunderbird 2.0.0.12 with the Enigmail 0.95.6 extension . This bug happens on 8.04 Hardy (beta release with full updates); I do not know if it happens on Gusty since I did not run this distribution.

Steps to reproduce:

1. Receive an e-mail encrypted with your public key. Do not read the e-mail.

2. Select the e-mail to drag-and-drop it to another folder.

Result:

- Mouse icon changes to "drag and drop" icon
- Thunderbird attempts to read e-mail (display the contents in the email text content box)
- The password prompt for decrypting the e-mail with the personal key pops up
- Entire system is frozen.

The mouse icon stays in drag-and-drop mode. The cursor can be moved but not clicked.
The small password prompt window has focus, but text cannot be entered in the box.
Both mouse and keyboard are entirely useless. I found it impossible to call either another window, the main menu, the task manager, or the "switch off" menu.
Other applications seem to be unaffected and apparently keep working in the background (ex: bittorrent upload).
The only way out is to power off the computer brutally.

For me, this bug is fully reproducible and predictable.

Package Details:

thunderbird 2.0.0.12+nobinonly-0ubuntu1 (as installed by "add/remove")
The Enigmail extension is 0.95.6, as re-used from my profile folder, imported from previous Linux installs (the extension was installed within Thunderbird). This is not the package available from Synaptic, which I did not know existed.
Ubuntu hardy 8.04 on HP nx7400 laptop, with full updates ran everyday.

Thank you for taking the time to report this bug and helping to make Ubuntu better. I tried this on Intrepid with thunderbird 2.0.0.16 and can't reproduce the behavior. Is this still an issue for you?

Hi and apologies for long delay. (e-mail is critical to me, finding time to fiddle around is hard).

This bug is still standing for me. It's not possible to take a screenshot, so I took a short video describing the problem:

If indeed this is not reproducible, or if it does not appear in Intrepid, please don't bother and re-close this ticket.
This bug is obviously not a big issue (at least for me) but it could bother (and scare) other people.

Thank you very much for your time.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release? Thanks in advance.

Hi duanedesign,

yes, the bug is still in effect for me right now.

I have Thunderbird 2.0.0.19 (20090105) on Intrepid Ibex.
The system has been upgraded from Hardy, and the Thunderbird profile is about 4 years old.

If you cannot reproduce the behavior, and wish to solve this, I can make a fresh Thunderbird install and try again. I'll make a fresh Jaunty install too, when it is out.

Thank you!
