The bottom lines:

=================   =============

It is not enough :(
You need to add

"Unix.*.Root.DynamicPath: .:$LD_LIBRARY_PATH  Unix.*.Root.PluginPath: :$QtRoot/plugins:$(ROOTSYS)/etc/plugins: too !!!

================= end of bottom line :) =============

The details are following:

The ROOT plugin is the regular shared library. As such it should be on your LD_LIBRARY_PATH too AND (!!!) it should be on

Unix.*.Root.DynamicPath

from $ROOTSYS/etc/system.rootrc.
See your
lcg/app/releases/ROOT/5.22.00b/slc4_ia32_gcc34/root/etc/system.rootrc:

 Unix.*.Root.DynamicPath: .:$(ROOTSYS)/lib"  Unix.*.Root.PluginPath: :$(ROOTSYS)/etc/plugins:

That means you should add two lines to your custom ".rootrc"

For example the STAR default value is

"Unix.*.Root.DynamicPath: .:$LD_LIBRARY_PATH Unix.*.Root.PluginPath: :$QtRoot/plugins:$(ROOTSYS)/etc/plugins:

This resolves us (STAR) all controversies.

LCG setting does not allow the user's defined plugins. By this reason, you need to customize your own ".rootrc"

Can you try that and make sure QtRoot lib directory is followed by $ROOTSYS/lib?

Have a nice day.
