OK dev/ammo42,
I'll try strace once I figure out how. Tim, in the mean time, I have rebuilt
all the x86_64 packages and I have captured a full debug of the issue with gdb.
Here is it:

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.

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:

Bummer... Think about what other tests I can do that might
disclose exactly what it going south... I'll open a bug report shortly :)
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:
http://bugs.trinitydesktop.org/show_bug.cgi?id=979
"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!
