problem

In a new client installation I got the following JS error (see rootcause error above) while demonstrating.

"Cannot read property 'query' of null" the error contains the spellcheck success handler.

According to the error message I assume the following problem:

1. Open a task and a segment
2. A spellcheck request is triggered
3. Leave the task before the spellcheck answer is back (can be faked with PHP sleep)
4. The above mentioned error should occur
