editing some files, and close one caused this crash.

my platform is kubuntu 10.10 with kde 4.5.1

and another thing, when i selected some text in one file, and swtich to another file, then switch back, the first selection in first file will be gone and auto cut to clipboard, every time this will happen!

The crash can be reproduced every time.
