Segfault in replace_link_contact

[Antoine Amarilli]

From trunk-1 revision 27, segfault when running on a file:
$ ./emailgraph -m ~/Mail/thunderbird/archives_b --dot

Here is the backtrace:
Program received signal SIGSEGV, Segmentation fault.

Please tell me about any additional information you would need.

This has been difficult to reproduce, but I have made some changes to the way that links are merged which might improve things. Try with version 0.5 and see if you still get the same error.

I tried with revision 35 from the repos, and I couldn't reproduce the segfaults anymore, so this works for me. Thanks!
