[Kolab-devel] [issue3678] Displaying a long inline pgp encrypted message takes very long

[Bernhard Herzog]

New submission from Bernhard Herzog <bh at intevation.de>:

When displaying an *inline* pgp encrypted message, kontact can take very long
(up to several minutes) to show the messages.  How long it takes depends on the
length of the message, but also on the content.  E.g. about 3MiB of normal
natural language text take about 20 seconds and a testmail where I encrypted
3MiB of base64 encoded data took more than two minutes.  While kontact is trying
to display the message, it is completely blocked and uses 100% CPU.

This also happens when Kontact cannot decrypt the message because of missing
private keys.  OTOH, when kontact cannot decrypt the message because it cannot
execute gpg 1.4 (because of unsupported config settings as in kolab/issue3319)
it only takes a few seconds.

Even a few seconds are a bit much, though.  Gnus for instance doesn't take more
than 1s to decrypt display the same messages.

Observed with kdepim enterprise branch in various versions, including
20090508.965262.
