[Java-gnome-developer] Slashtime 0.5.10 crash when closing About dialog

[Kenneth P. <ken...@gm...>]

Hey all, 

I was using the application Slashtime[1] while testing it for stability
and discovered a crash triggered by the About dialog. Triggering the
crash was simple: Simply launch Slashtime, open the About dialog, and
then click on close. This would cause the application to crash.

This behavior occurred on my desktop machine which was running
java-gnome 4.0.12. I double checked my laptop to confirm it wasn't an
environment fluke and found that it did not crash, but the
laptop was using java-gnome 4.0.11. I upgraded my laptop to java-gnome
4.0.12 to see if the new version was introducing the crash. It wasn't.

After a little bit of thought and since my laptop was slightly behind
in updates, I decided to upgrade gtk+ on my laptop (2.16.1) to 2.16.5
which is what my desktop was running. Slashtime then started crashing
as it did on my desktop. For confirmation I downgraded my desktop's
gtk+ from 2.16.5 down to 2.16.1 and Slashtime did not crash.

So as far as I can tell, the About dialog in Slashtime crashes when
closed when gtk+ 2.16.5 is installed but does not crash when gtk+ 2.16.1
is installed.

The question now is why is the About dialog crashing in gtk+ 2.16.5?

For reference I will include the crash output:
