[ltt-dev] ** ERROR **: Kernel/LTTV event size differs for event tree_call_rcu_bh

Hi,

You are not using the right version of the liblttvtraceread library.

The LTTng you were using produce files of the 2.5 format, but the lttv 
library are of the 2.6 version.

Maybe it's some artefact from a previously installed version of LTTV, or 
maybe you have installed a recent package. I would suggest that you 
remove any LTTV package and the liblttvtraceread in /usr/lib and that 
you reinstall the lttv version you want.
