runtime error trigger?

[kay22626]

I only post this in hoping it might help devs and/or skilled players in finding a solution for this problem.
I did not have any problem whatsoever since last patch(es), game worked perfect, not even a please wait.
Yesterday i had my only runtime error when quitting the game, and i think i actually provoked it by clicking insert to sit, while the "quit ryzom" timer bar was on screen.
Of course when i logged back my markers were gone and i had to redo a number of settings that were returned to default.
I logged in and out several times since and no runtime error.
