If you have a command line you would like me to run with strace, I'll take it,
otherwise, I'll report back with what I come up with. I hope this helps!

In my glibc-2.11 binary the objdump output tells me that
___newselect_nocancel() always does a syscall (you can recognise them
by the "int $0x80" instruction), so you should be able to retrieve the
parameters with strace.

Good Lord! Debug Packages are HUGE!!!
Nearly 600M of debugging symbols included in tqt3, tqtinterface,
tdelibs, tdebase. It looks like with will have to do this again on
x86_64, the i686 backtrace seems to stop early. However, it does
have line numbers for everything it caught:

I have opened a bug report and added this information to it:

"select buffer paste in kate/kwrite causing line wrap causes crash

Do you want me to begin a debug build on x86_64 as well? I can't
tell if this is enough of a backtrace to provide you with the
needed info. Let me know what else you need. Thanks!
Tim,
This is much worse than we thought. It effects EVERYTHING! Even
simply trying to view a text file in konqueror file management (kate
preview) will lock konqueror. Here is that backtrace too:

disclose exactly what it going south...
