Description FiNeX 2013-06-12 06:56:17 UTC

Application: kate (3.10.4)
KDE Platform Version: 4.10.4
Qt Version: 4.8.4
Operating System: Linux 3.9.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Kate started crashing after update to 4.10.4.

- What I was doing when the application crashed:

After a search&replace operation I've switched between opened files and Kate crashed.

More precisely the steps I'm using to reproduce the crash are:

1) start kate
2) open two files (A.txt and B.txt)
3) open search&replace panel on A.txt
4) do a search&replace operation
5) switch to the second file (B.txt)
6)  open search&replace panel
7)  do a search&replace operation
8) switch back to A.txt and click on the text area
9) switch again to B.txt and click on the text area
10) click on the search& replace line input fields (search and/or replace)
11) go back to A.txt and click on the text area.... Crash :-/

Probably the sequence could be shorter but I've not time to find a simpler pattern  :-)

I'm used to work with remote files and the auto recover feature doesn't work in this situation. I really hope to a quick solution because this bug doesn't let me to work and I'll have to switch to another text editor but I cannot find nothing better than kate :-(

The crash can be reproduced every time.

Thanks for the detailed steps to reproduce! Was hopefully able to fix it for KDE 4.10.5
