[Opensim-dev] System.InvalidCastException: Specified cast is not valid.

[Diva Canto]

Additionally to what Teravus says: not just LSL scripts (which seems to 
be the issue here), but some 3rd party tools for exporting content from 
SL seem to be using ',' for floating point numbers. This does not work 
in OpenSim. So please be careful with how you export SL content.
