friends-dispatcher crashed with SIGSEGV in flush_revision_queue()

[Alex Valavanis]

No idea what happened here, Apport just reported a crash... seemingly at random. I wasn't directly using the friends application.

Please let me know if I can do anything to help debug.

Looks like the segfault is coming from Dee. Nothing I can do to fix this from within Friends, I'm afraid.
