Thank you for your report. Kmail1 is currently unmaintained and the code has
changed sufficiently in Kmail2 so the backtraces are not really useful anymore.
Should you experience the same crash in Kmail 4.8.5 or later, please open a new
report for Kmail2. Thank you for your understanding

Yes, it is a known race condition,

I have the same error now (in linux). This is what I've done to get it hapen.

I just created an imap account, and selected a message, I was waiting for the
message to be displayed, while seeing thousands of lines:

kmail(15778) KMFolderSearch::slotSearchExamineMsgDone: "inbox" : serNum 60274
matches? false  

Then I choosed Quit, and this is the console output.

The problem with this bug is that it seem to occur when there is a dangling
kmail dbus session. I think that is the *real* bug. The point is that I'm not
able to reproduce that, although it just happened to me once also. What I had
by then is still a kmail session registered to dbus. But when trying to browse
the session using qdbusviewer it just froze qdbusviewer. 

However, when this does occur, the next thing happens when you try to start
kmail (the problem is in libkdepim/pimapplication.cpp I think):

Because their is a kmail session registered at dbus the test at line 70 will
pass.

Next the arguments are parsed at line 73, after this point it is not allowed to
add more options to it.

The problem starts when the test at line 93 fails and return
KUniqueApplication::start(); gets called.

Workarounds are: refuse to start when the test fails or call
KUniqueApplication::addCmdLineOptions() before the saveAppArgs() call in line
73.

But as said, these are just workarounds.

So I set a few breakpoints and here is where the application arguments are
parsed before KUniqueApplication::Start() is called:

I just realized that I had read the assertion backwards.  The problem is that
some code is forcing a parse of the command line options before
KUniqueApplication::addCmdLineOptions() is called.  I think this happens in
PimApplication::start() where it fetches the program name (argv[0]) before
calling KUniqueApplication::start().

Looking at the kcmdlineargs.h header, it seems that kmail is following the
documented procedure:

 * // Initialize command line args
 * KCmdLineArgs::init(argc, argv, appName, programName, version,
description
);
 *
 * // Define the command line options using KCmdLineOptions
 * KCmdLineOptions options;
 * 
 *
 * // Register the supported options
 * KCmdLineArgs::addCmdLineOptions( options );
 *
 * // Add options from other components
 * KUniqueApplication::addCmdLineOptions();

main():
  KCmdLineArgs::init(argc, argv, &about);
  KCmdLineArgs::addCmdLineOptions( kmail_options() ); // Add kmail options
  if (!KMailApplication::start())
 return 0;

and PimApplication::Start() trickles down to KUniqueApplication::Start() which
calls KUniqueApplication::addCmdLineOptions().  The example in the header
wouldn't set s->parsed = TRUE until later when KCmdLineArgs::parseAllArgs() is
called, so I think the example code in the header would always trip this
assert.
