Version: 4.8 (using KDE 4.8.0) OS: Linux I hate to be so unspecific but this one is hard to describe. From time to time - about twice a week I am spammed with messageboxes from KMail stating "Unknown error - No items found". And I find the inbox of one of my pop3-accounts containing a list of empty emails - (No Subject), unknown sender, unknown date - as in: completely shredded. I seeem to have lost about 150 mails this way and this really... sucks... The only thing I see when opening one of these mails is: X-CRM114-Version: 20100106-BlameMichelson ( TRE 0.8.0 (BSD) ) MR-646709E3 X-CRM114-CacheID: sfid-20120116_225406_819802_58555055 Message-Id: (sfid-20120116_225406_819802_58555055) X-CRM114-Status: UNSURE ( 0.00 ) X-CRM114-Notice: Please train this message. It looks like my spam-filter was handed the email already empty. Unfortunately I have no idea how to reproduce this, it just happens every now and then. Any pointer as to how to debug this would be highly appreciated, I want to be as helpful as possible to track down this bug. Reproducible: Couldn't Reproduce Steps to Reproduce: None, happens sporadically. My mails are eaten. Expected Results: My mails should not be eaten.
Well, I have been able to sorta reproduce the "No items found" error message, but the method is quite unorthodox, you have to be fast ;) The situation: create a folder and move a bunch of mails there. Before doing so try to put the system under load so the moving will take a little longer - i.e. akonadi(?) needs to be slow. This way, if you're fast enough, you can issue the move command a second time while the messages are still in their old folder. In other words: create two "overlapping" move actions for the same message(s). This way I got the "No items found" error to appear. No luck on getting emails eaten though.
...oh, even better: Create a filter without conditions and configure it to not be included in automatic filtering of any sort. Set the action to move into some temporary folder. Assign a shortcut to it so it can be issued quickly. Then select some mails and trigger the shortcut twice in a row. This will bring the "No items found" error quite reliably. Hope this helps some dev to maybe narrow this down.

Git commit d64d61b470c56b92294f6adee6d74305a217628d by Andras Mantia. Committed on 04/07/2012 at 17:35. Pushed by amantia into branch 'master'. A biggish refactoring of the filter functionality: 1) Do not take the items from the cache only, as they might be incomplete (especially in online imap case, but not only). This should fix the body loss bug on spam filtering.(Bug 287752 and similar ones + countless of reports on user list) Might fix 293768. 2) Download only what is really needed for the filter and add safety checks that the mail is not modified if the requested part is missing. So far the distinction was only betwee the body and rest. This should speed up filtering. Also related to 287752, but should fix also 292283, 288109. 3) Rename qDebug->kDebug + fix some includes 4) The code should also fix the duplicate mails appearing after filtering (some of the duplicates with empty content), eg. 275233 All bug reporters: in case you still see the bug, reopen the corresponding one. For the reports that were CC'd, but not closed, please try to reproduce and tell the result. So far the bug is fixed on master, but might be backported later to 4.9.

Git commit 8846d44b217108351c35f8afd883f72ee88388ec by Andras Mantia. Committed on 06/07/2012 at 11:12. Pushed by amantia into branch 'KDE/4.8'. Backport part of the filter fix: this is the actual fix, the rest were optimizations and safety checks, but it is difficult to backport. An unwanted side-effect might be that more data is downloaded than before, based on the type of filters used.
