Baho, All,

   I was working with the new Qt3 build on x86_64 and I ran into an xsession 
crash that I need help identifying the cause.  I have put the .xsession-error, 
trinity-qt3 file list up at:

http://www.3111skyline.com/dl/dt/trinity/err/newqt3/xsession-error-new-qt3.txt

http://www.3111skyline.com/dl/dt/trinity/err/newqt3/new-qt3-no-work-file-list.txt

   I have reinstalled an older build of Qt3 and it works fine, so there is 
something in the new build. The PKGBUILD is modeled after the one you are using, 
but I have enabled the doc and examples. I have put the PKGBUILD up here:

http://www.3111skyline.com/dl/dt/trinity/err/newqt3/PKGBUILD-qt3-trinity

   Looking at the xsession-error file, the following jump out at:

DCOP: register 'anonymous-1000' -> number of clients is now 4
DCOP:  'anonymous-1000' now known as 'kwin'
kdeinit: Got EXEC_NEW 'kdesktop' from launcher.
DCOP: register 'kdesktop' -> number of clients is now 5
DCOP: register 'anonymous-1001' -> number of clients is now 6
DCOP: register 'anonymous-1002' -> number of clients is now 7
DCOP: unregister 'anonymous-1002'

   I can't explain the first 2 error blocks, but the "dcop: error while loading 
shared libraries: libqt-mt.so.3: cannot open shared object file: No such file or 
directory" is self explanatory. However, if you check the file list link above, 
libqt-mt.so.3 is there:

07:36 alchemy:~/tmp> grep libqt-mt.so.3 new-qt3-no-work-file-list.txt
/opt/qt/lib/libqt-mt.so.3
/opt/qt/lib/libqt-mt.so.3.3
/opt/qt/lib/libqt-mt.so.3.3.8

   So, why is this file not being found?  I don't know what is causing this, so 
I'm punting to the smart folks for help. I'll have a bit more time to dig into 
this this weekend, but if you have any thoughts, I would appreciate any help you 
can give to shorten the dig :)
