If I understand it correctly, automatic duplicate bug marking is done based not on the bug description, but on the crash backtrace results (i. e., the program internals leading to crash).
The same code bug may be triggered by different conditions.

Your bug #1076830 doesn't contain a coredump retrace, and therefore is not very informative.
If you can reproduce it -- report it properly, with a coredump attached.
(If apport doesn't allow you to report the crash to Launchpad, please look at the bug 994921).
