32/64 bit OS?
gtk version?
can you get a stacktrace?

to get stacktrace you can use gdb or use Jive

Backtrace stopped: previous frame inner to this frame (corrupt stack?)


When I tried to investigate the bug, I think there's a problem when calling
        while (!shell.isDisposed ()) {
              if (!display.readAndDispatch ()) display.sleep ();
         }
I think it crashes right when it calls the shell.setSize(...) in the open( ...
) function of ClipboardExample. Couldn't trace efficiently the program since
gdb is reluctant to load the D symbols for some reason I couldn't really get,
so I just traced to where it crashed.

Sorry, the bug is not here, but in the setSize function .. however, I think I
remember I had the same bug a month or so ago, and it was crashing when the
shell.isDisposed() function was called.. maybe it's a kind of "random bug" 

hope you'll find it, I'd love to be able to use DWT !!

Can you please try to follow exactly the instructions from the quick 
install?  (if not already done)
http://www.dsource.org/projects/dwt/wiki/Installation#QuickInstallationonWindows
http://www.dsource.org/projects/dwt/wiki/Installation#QuickInstallationonLinux
Using exactly those downloads and versions.

On linux you can get good stacktraces with jive : 
http://downloads.dsource.org/projects/dwt/jive.zip

Most examples have a
version(JIVE) import jive.stacktrace;

When building those, give the additional arguements:
-version=JIVE -Ipath/to/jive -g

Jive needs the libbfd which is part of the package "binutils"

Well, if I compile the examples as written on your wiki page (ie. by including
the DWT source each time) it runs just fine, however, if I do dsss build &&
dsss install on dwt-linux, then try to compile the dwt-samples by dsss build,
it segfaults

I work with direct sources all the time. I found libs just making 
problems with no real benefit. The build time is not relevant faster and 
i have much less problems.
On the other hand with libs, i have to troubleshoot the build process 
all the time, keep several places uptodate, have to change directories 
more often,...
