Bug#684985: another backtrace, more explicit
Here it is below. You can see explicit call to text edition in thread
number 1.
Note that the bug does not only appear to new lines, but also when
adding text in some existing line (this backtrace).
I also would like to put a higher priority to this bug since kdevelop is
really unstable and does not allow me to use it safely.
