[Kolab-devel] [issue3837] Reproducible crash when (not) decrypting s/mime message

[Thomas Arendsen Hein]

New submission from Thomas Arendsen Hein <thomas at intevation.de>:

Kontact Version 1.2.9 (enterprise35 20090807.1015511)

When looking at an encrypted s/mime message the mail window looks like this:

---Encrypted message---
  This message is encrypted.
    Decrypt Message
---End of encrypted message---

Now I click on "Decrypt Message", pinentry-qt 0.7.5-2.1 asks for my passphrase.
In the background the mail window looks like this:
---Encrypted message (decryption not possible)---
  smime.p7m
---End of encrypted message---

Then I minimize the pinentry window,
click on the smime.p7m link in the mail window,
click on Open with 'Kleopatra',
confirm the error message (Invalid crypto engine) with OK,
close Kleopatra,
unminimize pinentry again.

When I now click on OK three times (without entering a password) or on Cancel,
kontact either crashes with the attached traceback or freezes until I kill it.

(Note that I do not need to minimize pinentry when the pinentry does not
obstruct the smime.p7m link, but in my default window layout it does)
