Cannot reproduce using 883447. I've configured an IMAP account. Can not reproduce at 883827 either. Assuming root cause has indeed been fixed in the meantime for now. *** Bug 175458 has been marked as a duplicate of this bug. *** Reopen.

I couldn't reproduce triggering this crash, but apparently it can happen in KMail. Benoît, can you reproduce this and if yes, how? BUG: 174992 M +3 -1 transportmanager.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=886171 Here is how this crash happened to me: with a completely new $KDEHOME, I ran KMail (svn checkout from yesterday), saw the first-time wizard, I configured my identity (real name + email address) and an IMAP account (with a server name for receiving and another SMTP name for sending mail). Then I clicked Finish, the wizard closed, and then the crash occured. I tried to reproduce it but failed. I removed share/apps/kmail* and share/config/kmail* in my KDEHOME, I got the first-time wizard again, filled the same information, no crash. So I don't know what in KDEHOME must be erased in order to reproduce the crash. As for the fix, I can confirm that I've been running it for a day without a crash; on the other hand I am having a problem where KMail doesn't actually manage to fetch any mail from my IMAP account and instead gets stuck forever trying to do it; I don't know if that can be related (I don't want to have made you introduce another bug in KMail !!) One more comment as to the "root cause" of this bug: In Configure KMail -> Accounts -> Sending, I can see *two* SMTP accounts created, but I only created one with the wizard. So we have at least a bug here, where the wizard creates the (same?) SMTP account twice. Now maybe this sounds familiar...? this bug here was caused by addTransport being called twice with the same transport, so if I understand correctly what a transport is, it's the same. Hoping this helps you by showing that the problem lies probably in the SMTP account creation part of the wizard... Just tried this again with qt-copy 884963 and KDE 887926 after throwing away the complete .kde4 directory. The casual user probably wouldn't note any difference since the crash still happens after the wizard completed, but the crash details are in fact completely different.
Btw. refering to the last comments: I only specified an IMAP server in the wizard dialog this time and NO STMP server which may or may not make any difference.
