323301 - enigmail plugin crashes Thunderbird completely when editing mails

Status: RESOLVED WORKSFORME

(Thunderbird :: Message Compose Window, defect)

Description

[Andreas Kleinert]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.8) Gecko/20051111 Firefox/1.5

The Enigmail plugin since some time crashes the message compose window very often when replying larger emails that were encrypted and when the reply also is preset to be encrypted (still present in v0.94.0.0 when used with Thunderbird 1.5 final).

Reproducible: Always

Steps to Reproduce:
1. Receive an encrypted eMail, preferably with multiple recipients and keys.
   Preferably more than one page of text.
   With or without attachments does not matter. PGP/MIME should be set to
   "possible".
2. Press "Reply all" and start editing the answer. Keep the encrypted checkmark
   set in the "OpenPGP" settings, but do not checkmark "Use PGP/MIME".
3. When heavily scrolling & editing text within the mail and marking blocks of 
   text it will crash in the middle of such an operation (less likely the typing
   process, but most likely the scroll-and-keep-text-marked-with-mouse
   operation).

It is easily reproduceable with one and the same mail if you try it multiple times. The only workaround that helps is, to close the mail every few minutes so that a draft is saved in the "drafts" folder. Then re-open it again from there and continue editing.

The problem is, that Thunderbird crashes completely and thus otherwise no copy of the draft is saved. The quality feedback agent instead is started and the normal Thunderbird input is blocked.
Actual Results:  
see above

Expected Results:  
see above

At least it would be nice if it would not crash completely. The problem therefore does not seem to be only in Enigmail but also somewhere in the plugin interface.

Would it be possible to save a copy of the "currently being edited" email in case it really is not possible to avoid a program restart? Is this something the quality feedback agent could manage? (*)

(*) similar to the autosave feature some text processing software offers, but a bit more sophisticated

Please post the talkback IDs here. They are in extensions\[e-mail]\talkback.exe, which is located wherever you installed Thunderbird.

Using 1.5 final (de) with the newest enigmail, Thunderbird no longer crashes but deletes the mail I am editing. This scenario affects only if I'm using the Delete-Button, other actions work properly.

Using Thunderbird up to 1.5.0.7 with enigmail 0.94.1 no crash since months!
