script - RPR_GetSetTrackState trashes fx info?

hi there,

i had a shot at a script to automatically add track icons to a project. i've got it working, but running a diff on the project before/after shows that a lot of stuff is disappearing.

i'm using python 3.1.

basic method:

* reading raw track data using RPR_GetSetTrackState
* modifying the track data
* writing back using RPR_GetSetTrackState

if i write a function that just reads and writes back the track data without editing or changing anything, it gets trashed pretty bad when the track data is large, even if i set a huge read buffer as the third param (verifying that the input buffer is large enough).

i've attached a script and a project that reproduces this. running the script will mangle the project (it gets 90% smaller!).

it only seems to affect VSTs with lots of embedded data (e.g. romplers/samplers). plugs like ReaEQ come across fine.

also, note that the reascript spec seems a bit wrong wrt the GetSetTrackState function.
