Several times docky crashes, with this same problem and I don't know why...

I have terminaled it and got this:

$ docky

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

I hope it may help to find the solution.

But by my eyes I believe some problem is going with the Gmail check app in the docky, every time it crashing when it's trying to fetch my mails (but not always)
