[Pkg-mozext-maintainers] Bug#893791: enigmail: Enigmail freeze (100% cpu load) on encrypted PGP/MIME attachments

[Karl Kashofer]

Package: enigmail
Version: 2:1.9.9-2
Severity: important

Dear Maintainer,

   * What led up to the situation?
Encrypting or decrypting a PGP/MIME encoded attachment with size > 5mb freezes
Thunderbird.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Sending a message with attachment to be PGP/MIME encrypted or decrypting a
PGP/MIME encrypted message with a attachment >5mb.
CPU rises to 100% for several minutes, Thunderbird is unresponsive, Gnome wants
to kill it multiple times.

   * What was the outcome of this action?
It works in the end but takes ages, lots of CPU and Thunderbird is unresponsive
until its done.

   * What outcome did you expect instead?
Fast de/encryption, it works when using PGP/Inline.
