           Summary: sending a message hangs after server connection is
                    reestablished
           Product: kmail
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: nisavid at gmail.com


Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
it often happens that KMail will pop up an annoying message saying "the
connection to the server could not be established", or something along those
lines, when performing an automatic mail check. this is despite the fact that
my network connection is fine---of this i am certain, since i've checked my
mail manually through a Web client immediately before, during, and after this
message has popped up.

by itself this message isn't terrible since KDE's focus-stealing prevention
usually prevents the message from interrupting me (except, notably, when i am
running some applications in wine). it is annoying that i need to close it
every time, which is numerous times per day. however, it seems that a
consequence of this occurrence is that sometimes any subsequent messages that i
attempt to send through KMail will hang indefinitely at 0%. i can click the '-'
button to cancel the process, but the grayed-out message window remains. i can
then click the close button on the message window, which prompts me to save a
draft, but regardless of my choice, the window remains in its grayed-out state.
the only way i have found to work around this is to kill KMail. it was such a
workaround that produced the included backtrace.
