The following assertion was thrown during method call TextInputClient.performSelectors:

Failed assertion: line 960 pos 12: 'range.start >= 0 && range.start <= text.length'

Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
