Crash every hour

Hello,

Sonarr has always been working pretty well for me (develop version) on Ubuntu 14.04 with mono 3.10.
But since a day or two i keep getting crashes every hour or so, the only thing i can find in the logs is:

15-4-22 13:00:57.0|Fatal|GlobalExceptionHandlers|EPIC FAIL: Object reference not set to an instance of an object

System.NullReferenceException: Object reference not set to an instance of an object
at System.Threading.Timer+Scheduler.SchedulerThread () [0x00000] in :0
at System.Threading.Thread.StartInternal () [0x00000] in :0

This always seems to happen in logs right after:
15-4-22 13:00:32.6|Info|RssSyncService|Starting RSS Sync
15-4-22 13:00:56.7|Info|DownloadDecisionMaker|Processing 700 reports

Any idea on this?
Thank you.
