gdb help - backtrace for kwin KDE4.04 bug (still present)..


I have asked this question pretty much all over the internet but have
never had a response...

There is still a very nasty bug in KDE 4 that on some Nvidia cards
crashes KDE (and locks up the machine style..)

- see bug :-

'Bug 157282 - Looking glass magnifer and sharpen OpenGL Desktop effects
crash/do not work on multiple systems'

I am unable to use gdb to provide a backtrace, i'm nearly there but
must be doing something wrong..

This is what i am doing

From console in kde (as root)

# ps aux | grep kwin (to find kwin pid)

# gdb kwin (pid)

- at this point i am unable to click on anything (as kwin is frozen..)

I turn logging on by

# set logging on

I then try to debug by using

# continue

- after using continue I can start to use kde (kwin) again, however no
more output is created.

Can someone please point me in the right direction I must be doing
something wrong, or even better provide example lines that they would

- i have the debug RPMS's installed...
