           Summary: Random dimap data loss (most old messages are removed)
           Product: kmail
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: unspecified
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: reinhold at kainhofer.com


Version:            (using KDE 4.3.5)
Installed from:    Ubuntu Packages

It has happened three times during the past year that KMail almost completely
cleared either the INBOX (once) or the calendar folder (twice). Unfortunately,
I cannot give any concrete steps, just some observations that might help
finding the area of the problem:

-) I'm running three computers (office PC, home laptop, eeepc), with all three
running kmail and auto mailcheck at all times.
-) The problem happens only on the eeepc, which is the only computer where I
user suspend to RAM (while kmail is running). In all cases where a folder was
almost cleared, I had used the eeepc shortly before (and the message removal
probably happened then).
-) In all cases, the folder was not entirely cleared, but some messages were
left in the folder. These were newer messages, while all the old messages were
removed from the inbox / the calendar folder. Most of the remaining
messages/events were created/received less than a week before the incident
happened, but some older are also preserved (although none older thatn 6.5
weeks is preserved).
-) It is not the same problem as bug #230699, since old/existing mails are
deleted from the server, too.

Unfortunately, these are all my observations. I'm sorry I don't have any more
details on the problem, but it appears randomly and only seldom, so it's hard
to track.

Unfortunately, such data loss is about the worst that can happen (I had several
appointments for vocal auditions including all contact information in my
calendar, when kmail decided to almost clear my calendar folder... It doesn't
look too professional that I have to call them -- if I can get their phone
numbers again, that is -- and ask again about the details!)

Currently, the only thing that is keeping me with KMail is that KOrganizer is
the only calendar application that can print out beautify weekly timetables
(and since I'm using three computers, I need a groupware solution, so dimap
over KMail is required.)
