Hi,
I don't have too much time to debug this right (sorry), so I'm
sending it here.
Double-click on the about:splash page a few times (especially at the
very bottom), and you'll get this crash easily enough:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 16384 (LWP 23106)]

334 while (eit1->stack[nea]->widget == eit2->stack[nea]->widget) {
Here is the backtrace:

The following test fixes this for me, without any apparent
side-effects. I'm still not very familiar with the selection code yet,
so it's just a suggestion for Sebastian.. this might be breaking
something else. The little patch:
