[Shotwell] Problems in Ubuntu 12.04

[Hernan Javier Lopez]

Launching Shotwell in Ubuntu 12.04 64bit, I closed after opening.
Launched from the console, the message he gives is as follows:

~$ shotwell
**
ERROR:/build/buildd/shotwell-0.12.2/src/DirectoryMonitor.vala:511:directory_monitor_real_internal_notify_file_discovered:
assertion failed: (updated)
Abortado (`core' generado)

Thank you very much
