Application: kwrite (4.4.5 (KDE 4.4.5))
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-55-generic x86_64
Distribution: Ubuntu 10.04.4 LTS

uname: Linux 2.6.32-55-generic #117-Ubuntu SMP Tue Dec 3 17:31:12 UTC 2013 x86_64 GNU/Linux
kwrite 4.4.5 russian.

When I replaced esc-lines "\n" to "' " (newlines to quotes and spaces) kwrite killed. If replace "\n" to "' '" (newline to quote+space+quote) - all right. But if last character - space - kwrite kill. Use button "replace all".
