[Decibel] segmentation fault

[George Goldberg]

Whenever I set the presence of an account to offline (1) I get a
segmentation fault from the decibel daemon
resulting in this backtrace.

Its 100% reproducible on my system. steps:
- start decibel daemon
- add an account using ./decibel_registeraccount_demo ...
- bring it online ./decibel_setpresence_demo 1 2
- take it offline again ./decibel_setpresence_demo 1 1
- decibel daemon crashes.

I'm not very good with backtraces, so I can't work out
what is causing this crash. If anyone can tell me, or even reproduce
the crash (if not then I'm probably doing something wrong to cause
the crash) that would be great.

Thanks

George Goldberg
