Application: kate (3.4.3)
KDE Platform Version: 4.4.3 (KDE 4.4.3)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.12-115.fc12.i686.PAE i686

-- Information about the crash:
Excuse me for my english.
The title is a bit cryptic, I'll describe the crash a little better. 
I open kate and select the saved session i need, then I close the first file I have in view, then kate crashes.
Possible reason:
When I close a file, kate shows me the 'last accessed file' before the one I'm workin on. But, if I open kate and close the current file, kate doesn't have a 'last accessed file' list, or better, the last accessed file list is empty, so (maybe) it try to activate a 'null' list entry.



The crash can be reproduced every time.
