I went through all addons, but in the end it seems to be the startup and userpref files I was using. I've binned the old ones and made new ones, but they still make blender crash for some reason.

userpref.blend

startup.blend

I can't reproduce the crash with the user preferences and startup attached. Do you mind also prodiving a .blend file with curve just before adding mirror modifier?

Here is a .blend just before adding a mirror modifier.
Attached is also my 2.70 folder from C:\Users<USER_NAME>\AppData\Roaming\Blender Foundation\Blender
containing all my settings and addons.

@Kungen

Cant redo the crash, tested with your files from (https://developer.blender.org/T40434#15)

I get this error with your startup file when left clicking:

  RuntimeError: class WM_OT_enhanced_3d_cursor_registration, function modal: incompatible return value , str(, Function.result expected a set, not a NoneType)

I switched to the new Blender 2.71 testbuild2. Problem gone.
Thanks for the help, though. I was really impressed by the attention this got!
