Version:           1.5 and CVS HEAD (using KDE Devel)
Installed from:    Compiled sources

OS:          Linux

I have a mail account on an IMAP server.  The name of the SMTP server I use to send mail is identical to the server name of the IMAP server.

When launching KMail, the entire GUI of KMail displays and then an Information dialog box pops up with the following message:

"Error while creating file .mailboxlist: File exists"

After clicking OK in this dialog box, another one appears with the following message:

"Error while creating file .mlbxlsttmp: File exists"

After clicking OK in this dialog box no other errors occur and KMail performs fine without any apparent problems.

No files named .mailboxlist or .mlbxlsttmp exist on my system.  I have read that these files may exist on the mail servers themselves.  However, I am able to read my IMAP mail in many email clients on multiple operating systems without problems.

The same problem occurs in both the version 1.5 of KMail distributed with Mandrake Linux 9.1 and KMail compiled from CVS HEAD.  You can reproduce the problem by restarting KMail.

Here is the full output sent to the console:
