[issue11170] (MacOS X) Crash on non-english language keyboard input in Text widget

[didzis]

New submission from didzis <g_didzis at inbox.lv>:

In simple text edit trying to input non-english characters with keyboard ends with a crash on MacOS X (10.6).

For example, to input Latvian language characters, apostrophe should be pressed followed by some letter (a, e, i, u, k, l, ...)

Tkinter crashes immediately after apostrophe was pressed on keyboard.

Terminal output:
