Segmentation Fault on dump file load.

I have dump file that is causing a segfault on the automatic collapsing step.

The dump file was generated in my code as follows:

...
 214 from meliae import scanner
 215 self.l.info(" Start dumping ...")
 216 scanner.dump_all_object("meliae.dump")
 217 self.l.info(" End dumping")
...

Then when I try to open it:

>>> from meliae import scanner
>>> from meliae import loader
>>> om = loader.load('src11.dump')
loaded line 148754, 148755 objs, 17.3 / 17.3 MiB read in 3.7s
set parents 148754 / 148755
Segmentation fault 148755 collapsed 1305

How can I attach the dump file?
