Yup. However, this is just the single list where network-wide search  
results are displayed. Furthermore, in this particular case, the callback  
took time because the network didn't return any results (it tries for 2  
seconds) which indicates some data inconsistencies (IOW: shouldn't happen  
in Real Life, at least not regularly).

But performance/responsiveness aside, any idea what causes the crash&burn?
