           Summary: kmail segfaults when checking for new mail
           Product: kmail
           Version: unspecified
          Platform: Debian stable
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kmail@kde.org
        ReportedBy: b_rogers@wfec.com


Version:            (using KDE KDE 3.1.1a)
Installed from:    Debian stable Packages
Compiler:          gcc 2.95 
OS:          Linux

I just upgraded a Debian woody to KDE 3.1.1 from KDE 3.1.1.  Since upgrading, kmail \
consistently segfaults when I check for new mail.  It appears to successfully \
retrieve the mail OK.  I see the new counters increment in various folders before it \
crashes.  After restarting, the folders do not show new mail unless I enter the \
folder at which time the new counters immediately update and the new mail is present \
in the folders.  Any check for new mail crashes again, whether manual or interval.

I see the same behaviour with Ralf Nolden's debs from kde.org and with an executable \
I compiled with debugging enabled.  Backtrace follows.  Hope it helps.
