kate (3.6.5) on KDE Platform 4.6.5 (4.6.5) using Qt 4.7.2

- What I was doing when the application crashed:

The same as similar bug reported by me before.

Tomas, can you please quickly build Kate by following http://kate-editor.org/get-it/ and check, whether it still crashes then?

Ok, then please type:
  git checkout 7f71b032be9aee12a3666565984f01fa671e7098
after the initial clone, and then continue with the cmake calls. Does it compile now? If so, can you reproduce the initial report?

After above I run kate like:

valgrind --track-origins=yes --num-callers=25 kde/run.sh kate

I tried again create a crash but kate hung up and not response.

kate use 50% my cpu, but I have intel core duo, so It will be 100% of first cpu.
Next I killed it by xkill.

Correct is:

Can you run this again?

OK. Kate run really slow.
I attached 2 files.
I edited python file (more that 1000 lines), one class with lots of method and docstrings:

Example:

class API:

     def x(self):
         """my description
Input: {
     "dfdf": "dfgfdg",
     {
         "sfd": "dfgdg",
     }
}
         """
         some_function()
         return True

To generate errors I collapsed methods below, next I cut selected string (CTRL+X) area:
----------------------------------------------
         fd": "dfgdg",
     }
}
         """
----------------------------------------------
and press CTRL+Z.
Do this repeatable.(collapse/uncollapse this method/docstring and methods bellow)


katelogs.txt => without hung up, but I can not scrollbar to the bottom of text. The scrollbar was too short:(
katelogs2.txt => with hung up, before I see only (blank page) background without any chars. After pressed "page down" kate hung up.

Best Regards,
Tomasz Narloch
