Addendum: after the filter agent crashes, mail will no longer filter, and I have to restart Akonadi to get filtering working again.

[Joshua Kugler (jkugler)]

Another addendum. It seems if I get mail filter running, I can filter one message at a time. But if I select too many to filter, and then hit 'Ctrl-J' it dies.

[Joshua Kugler (jkugler)]

Or it dies if I hit 'Ctrl-J' too fast. Siiiiigh. So aggravating. All this was working perfectly with KMail 1.

akonadi_mailfilter_agent (4.9) on KDE Platform 4.9.00 using Qt 4.8.1

I was trying to filter by hand (i.e. Ctrl-J) and selected a block of messages (eight) and hit Ctrl-J. and the mail filter crashed.

[Joshua Kugler (jkugler)]

Changing to critical importance because it renders filtering unusable. With over 100 filters, I heavily rely on filtering to work properly.

I can't find the place to link to the upstream bug, so here it is: https://bugs.kde.org/show_bug.cgi?id=304866

[Joshua Kugler (jkugler)]

These are using the 4.9.0-0ubuntu2~precise1 PPAs by the way.

[Mark Fraser (launchpad-mfraz)]

Might be related to this bug I filed a while ago https://bugs.kde.org/show_bug.cgi?id=302567. It is marked as fixed, but I'm still seeing the crashes occasionally.
