Bug 247331

Application: kwrite (4.4.5 (KDE 4.4.5))
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32.16-150.fc12.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
i put the full chemical moniker of titin on a single line (about 200k letters)
and i went to the front of the word ( just used the home key ) and deleted the line-return above it.
so basically, the word was on line 2, and i erased line 1 by hitting backspace.
i did this really quick, and it crashed kwrite.

 -- Backtrace:
Application: KWrite (kwrite), signal: Segmentation fault
