EventLog function can handle string,integer class and long class. (in android_util_EventLog.cpp)
If menu title string are used bold tag(like <b>test</b>), it'll be android.text.SpannedString.
In onOptionMenuSelected, it is using item.getTitleCondensed() function for writing event log.
therefore any android activity using tag menu string(like <b></b>) can be crashed by IllegalArgumentException.
I found this crash on GMS Application.
change locale chinese -> launch Google+ -> hangout -> menu key -> Invite(expressed chinese) click -> Google+ crash
