Description Giampaolo Gallo 2002-12-11 10:28:16 UTC

Version:           1.5 (using KDE KDE 3.0.99)
Installed from:    Compiled From Sources
Compiler:          gcc 3.2.1 
OS:          Linux

I'm using kde 3.1rc5 compiled with gcc 3.2.1. I'm using qt-3.1.0 glibc 2.3.1 on linux 2.4.19.
May be this is related with the bug # 48980. I am kmail with an imap account on a laptop. When I move from an office to another, the ip address of my machine changes. I must close and reopen kmail because (I think) of active processes related to kmail/imap that maintain the old route to the server. Kmail takes a lot of time to close (3/4 minutes). Then issues the following backtrace

Comment 1 Ingo Klöcker 2002-12-11 11:33:35 UTC

The backtrace you provided doesn't contain any useful information. Please recompile KMail with 
full debug information (i. e. use the --enable-debug=full option when configuring kdenetwork).

Comment 2 Giampaolo Gallo 2002-12-11 16:25:48 UTC

I recompiled kdenetwork and got this (the same as before, statement numbers 
apart).Moreover I noticed that kmail/imap keeps the connection to the imap server constantly 
open. If the network configuration is changed and the user closes kmail after the change the 
kmail child process that talks with the imap server does not die (at least not immediately), and 
I must kill it. If not kmail is not able to read from the remote imap mailbox.
