Version: 3.2.2 (using 4.2.2 (KDE 4.2.2) "release 111", KDE:KDE4:Factory:Desktop / openSUSE_11.1) Compiler: gcc OS: Linux (x86_64) release 2.6.27.21-0.1-default Start kate, open new session, and select File->Quit. Kate crashes with a useless backtrace.
Then try other debugging tools (valgrind, kdebug output) or find someone that can reproduce this and doesn't have a broken backtrace. Without more information this bugreprort is completely useless.
Or a developer like your self could run kate and select File->Quit instead of posting rude comments. ==4220== Invalid read of size 8 ==4220== at 0x6EE0E62: (within /usr/lib64/libQtGui.so.4.5.0)

valgrind trace provided
How should I produce a backtrace or valgrind log if I can't reproduce the problem? And looking at the backtrace and the comment about gdb producing garbage backtrace this seems to be simply a broken Qt installation. There's most probably some kind of binary incompatibility. Is this a package, if so I suggest to complain to the package developers. If you've built yourself then remove the installed files, remove your builddirectories and start a new build from scratch.

Hmm, this seems to happen only with trunk, not with my 4.2 (checkout is pre 4.2.2 iirc)/Qt4.4. Vadym are you running KDE 4.2.2 on Qt4.5?
I can reproduce this with KDE trunk (same backtrace)
I can reproduce this bug on KDE 4.2.2 qith Qt 4.5.0-2 of Debian testing/unstable. I've installed kdebase-runtime-dbg package.
