When KMail starts up as part of a restored session at log in (and not when started from Kickoff, say), it asserts with the following backtrace:

This happens every time I log in when I had KMail running at logout.  Something appears to be trying to access the first KMainWindow before any have been created.

It happens when it tries to ask for a password, it seems.  Something that may be related is that for one (out of three) of my IMAP accounts, I get asked for the password every time I start KMail despite telling KMail to remember the password.  The other two accounts remember the password without a problem.
