Patch files

I cannot choose the version i really use.
The right version i use is WebKit-r68833.tar.bz2.
I want to use "E-Texteditor" under Ubuntu 10.10 X86_64. Compiling Webkit is a part of this.
I also have to patch the files with attached patches.

Compiling works great.

But when i try to use the WebPreview Feature twice time in any way in E-Texteditor, the program crashes with the following error:

read(5, 0x32ee424, 4096) = -1 EAGAIN (Resource temporarily unavailable)
read(5, 0x32ee424, 4096) = -1 EAGAIN (Resource temporarily unavailable)

write(2, "ASSERTION FAILED: vptr() == JSGl"..., 54ASSERTION FAILED: vptr() == JSGlobalData::jsArrayVPtr
) = 54
write(2, "(../JavascriptCore/runtime/JSArr"..., 77(../JavascriptCore/runtime/JSArray.cpp:220 virtual JSC::JSArray::~JSArray())
) = 77
--- SIGSEGV (Segmentation fault) @ 0 (0) ---

Speicherzugriffsfehler

I think it's caused by Webkit cause JSArray.cpp is a part of this project.
Maybe you can help me.
Thanx a lot.
