100% CPU usage in Find-Dialog

If the search logic is set to "RegExp" search and you type a backslash as first character, creator hangs with 100% CPU usage.

To reproduce:
Having set the search logic to normal mode,, type in "\bfoo\b", set the logic to "RegExp" and hit the "find next" arrow button. Then close the find dialog and open it again using CTRL+F.
Now type a backslash ("\") -> Creator's cp usage goes up to 100%.
