Qt Creator crashes when click-dragging lots of selected text block into another text block

I started getting random crashes in Qt Creator and have narrowed it down as much as I can. Here are the steps to reproduce:

1. Open the attached .cpp file in Qt Creator.
2. In the line "const int someBigIntArray[] = {", double click to the right of the "{", which will cause the whole block to be selected.
3. Click in the selected region (e.g., directly on the "{" ), and drag your mouse to begin the process of moving the text elsewhere.
4. Drop it inside of the "

" block. Qt Creator should crash.

Notes:
-It only happens if you're dragging many lines of text. If you delete most of those 0's so that there are only a few left, it won't crash. If you can't reproduce the bug, try adding more 0's until you have perhaps a few hundred.
-It only happens if you drop the text inside the array initialization block. For example, if you drop it somewhere inside the text "const int someBigIntArray[]", it moves the text properly and no crash occurs.
-It only happens If you are NOT copying the ';'. Dragging the text WITH the semicolon works properly.
