iPhoto crashes when I write name on people's faces. Can I solve this problem?

Try this: launch iPhoto with the Option key held down and create a new, test library. Import some photos and check to see if the same problem persists. If it does make a temporary, backup copy (if you don't already have a viable backup copy) of the library and try the following:

1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your

User/Home()/Library/ Preferences folder.

2 - delete iPhoto's cache file, Cache.db, that is located in your

User/Home()/Library/Caches/com.apple.iPhoto folder.

3 - launch iPhoto and try again.

NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto. You'll also have to reset the iPhoto's various preferences.

If the problem didn't repeat in the new library then your current library is damaged. In that case make a temporary, backup copy (if you don't already have a viable backup copy) of the library and apply the two fixes below in order as needed:

Fix #1

Launch iPhoto with the Command+Option keys held down and rebuild the library.

Select the options identified in the screenshot.

Fix #2

Using iPhoto Library Manager to Rebuild Your iPhoto Library

Download iPhoto Library Manager and launch.

Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.

Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option

In the next window name the new library and select the location you want it to be placed.

Click on the Create button.

Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
