zeitgeist-daemon crashed with OverflowError in call_async()

Please see this merge request from Michal in order to grok what's going on here: https://code.launchpad.net/~mhr3/libzeitgeist/various-fixes/+merge/31801

And do give a round of applause for some top notch debugging from Michal there :-D

For the record: In order to close this bug in Zeitgeist (not libzg) I think we need to do as Michal suggests; wrap the monitor invocations in try-catch blocks.

Closing it in libzg is a matter of merging Michal's branch

Looking quickly at fixinf this on the ZG side as well... I am actually afraid that this is impossible to fix inside Zeitgeist :-S

We dispatch the monitor DBus calls asynchrously, and the bug is somehow picked up very low in the stack in an async callback before it reaches Zeitgeist. Indeed I can see no Zeitgeist code in the stack trace. Also, we are actually passing in an error handler to DBus which *ought* to be invoked on errors, but apparently not, since that should simply result in a warning printed on stdout.

@Mikkel: I'm afraid this will be different issue, the reporter states that only thing running was GAJ, and due to the date this was opened (April), it's impossible that a libzg monitor caused this. Also here's a traceback which caused the libzg bug, it's a bit more clear than this one.

So as far as I understand here there is no way for us to fix it in Zeitgeist... I will mark this as "Won't fix" and feel free to re-open it if you disagree withe me.
