[issue152] kmail crashes when fetching encrypted mails

[Bernhard Herzog]

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

KMail (aegypten_2_0_0_pre3_release from yesterday) just crashed on me when
looking for new mail.  Apparently it was after the email had been fetched and
put into the inbox, because starting kmail again produces the same crash.  I
could briefly see that apparently all new emails were encrypted.  The taceback
is the same in both cases:
