installing qtwrt (1.1.0) failed...
module wrt-api produced about eleven (11) segfaults, one for each(?) API.
when removing, same happened, 11 segfaults, but finally everything wrt was removed.
then I installed the older qtwrt-experimental, with no problems.
just my experience, don't know if this here is the right place to report this.
I have N900 with PR1.3, standard kernel, nothing special.
