Description:
In a Writer document with several large photos and text boxes keyboard entered characters arrive in the document in the wrong sequence.  type 'abcdefgh' on the keyboard and get 'acbdefgh'.  If you type really slow it does not happen.  If you type fast it happens.  It appears that some part of the character processing is using threading and the tasks are getting out of sequence.

Steps to Reproduce:
1.create a document with large pictures inserted
2.insert a text box 
3.type something fast and it will be out of sequence

Actual Results:  
characters are entered in the document slowly and out of sequence

Expected Results:
characters from keyboard are displayed in the correct sequence


Reproducible: Always
