I cannot reproduce the problem here. Could you post more detailed steps to reproduce?
You might also have better chances of getting the bug fixed by filing a bug report upstream at [1]. It would great if you could do so and post a link to the report here. Thanks.

Comment 13 Kevin B. 2013-11-22 15:42:19 UTC 
It looks strange for me because I cannot reproduce it anymore now !

A just take a C code from a colleague and I started to "clean" it by adding some header file, etc. When I put the #ifndef and then #define, I just wanted to go to the end of the file by pressing "page down" or "down arrow" in order to put the #endif and at that moment QtCreator freeze.

I happened to me 3 times, I was able to reproduce the freese... but I continue to code, and now it's gone :/

I'm sorry not to be able to help you more...  if the bug come again, I will post on qt-project + link here, yes.

Thanks
Comment 14 Sandro Mani 2013-11-22 15:50:13 UTC 
The Qt-Creator 3.0 release is also upcoming (beta currently packaged in rawhide). You might also want to check with that release if the issue appears again. I'm closing this bug for now, if you encounter the issue again feel free to reopen. Thanks.
