New problem.

   I've tried various combinations of traces between two machines, using 
writeTraceLocal and writeTraceNetwork.  All of the network traces, when 
imported into LTTV or the Eclipse LTTng perspective, cause the viewer to crash 
without any warning.  Eclipse's log(s) is(are) empty, it just detects "The 
workspace exited with unsaved changes in the previous session; refreshing 
workspace to recover changes" when relaunched.  I strongly suspect some kind of 
corruption of traces done in network mode, but I must also protest the very 
poor exception control that these tests reveal.

   Subsets of the network traces can be imported and viewed as long as the 
following sub-traces are left out: fs, kernel, mm, net, pm, rcu, and vm_state.  
The remaining ones (block, fd_state, global_state, ipc, irq_state, jbd2, 
kprobe_state, module_state, netif_state, softirq_state, swap_state, 
syscall_state, task_state, userspace) appear fine.  The pm sub-trace crashes 
Eclipse's LTTng viewer for one trace but not the other (the two traces are of 
different machines).

   A (likely unrelated) problem is that if I try to import a "safe" sub-trace 
alone (without the metadata), I get an alert "Unrecognized/unsupported trace 
version: Library reported trace version 200.121 [...]".

   Should I file a bug report (or two) and upload one of the offending traces 
as a bug attachment?  Anything else I can try?  Any other way of validating the 
trace file contents?
