Crash traceback:

---------------------------------------------------------------------------
TypeError                              Python 2.5.1: C:\Python25\python.exe
                                                   Tue May 06 22:26:51 2008
A problem occured executing Python code.  Here is the sequence of function
calls leading up to the error, with the most recent (innermost) call last.

C:\Python25\scripts\ipython in <module>()
     12 IPython.Shell.IPShell().mainloop(sys_exit=1)
     13 
     14 [or simply IPython.Shell.IPShell().mainloop(1) ]
     15 
     16 and IPython will be your working environment when you start python. The final
     17 sys.exit() call will make python exit transparently when IPython finishes, so
     18 you don't have an extra prompt to get out of.
     19 
     20 This is probably useful to developers who manage multiple Python versions and
     21 don't want to have correspondingly multiple IPython versions. Note that in
     22 this mode, there is no way to pass IPython any command-line options, as those
     23 are trapped first by Python itself.
