[Kde-pim] mailfilter does not see all incoming messages

[Wolfgang Rohdewald]

using KDE master

my filter for incoming mail does not get noticed of all new mails.
if I get 10 mails (sent by myself from somewhere else), between 0 and 3
remain in inbox. The ignored mails are always some of the last ones,
the first 5 mails always get through to mailfilter.

I added some debug output to MailFilterAgent::itemAdded and now I can
see that this agent indeed does not receive all items. Whereas the
nepomuk feeder does. In the log below, mailfilter does not get item 177.

Where should I search for the problem? I already tried to make the 
Akonadi::Monitor in mailfilter more similar to the one in nepomukfeeder, but
that did not change anything. mailfilter ignores items with wrong mime-type,
but I verified this is not the problem.

The message "1 item create jobs are pending" seems interesting but the
number of pending messages most often does not correspond to the
number of  missed items.

and these are the changes I tried on mailfilter, generating the above output:
