Comment 6 for bug 949808

Though this solution works, sikuli will abort the program some times when trying to find a string from screen or invoke text() method for the screen:
------------------------------------------------------------------------------
[log] RIGHT CLICK on (1120,835)
Using substitute bounding box at (31,0)->(71,16)
java: unicharset.cpp:76: const UNICHAR_ID UNICHARSET::unichar_to_id(const char*, int) const: Assertion `ids.contains(unichar_repr, length)' failed.
/home/tiddy/bin/jython: line 263: 11795 Aborted (core dumped) "${JAVA_CMD[@]}" $JAVA_OPTS "${java_args[@]}" -Dpython.home="$JYTHON_HOME" -Dpython.executable="$PRG" org.python.util.jython $JYTHON_OPTS "$@"

------------------------------------------------------------------------------

BTW, after the error, I cannot type via keyboard in the Terminal, and also failed to paste text in the Terminal. I have to close the current Terminal to restart.
