Well, I see, this happened due to error loading fbtrace.

Certainly, it's better to have diagnostics instead segfault :)

Well, please take a look at this function (in PluginManager.cpp):
RefPtr<PluginModule> PluginSet::loadModule(const PathName& asIsModuleName)
It tries to load a module, but if fails - checks, if file is loadable
from mod_loader POV. And if yes, but failed to load, reports an error.
In you case it looks like fbtrace is loadable, but anyway can't be
loaded. I.e. something like unresolved external reference in it.
