Hi!

I think it would be a great idea, to have in the Effects menu a testing effects option. If someone click on this menuitem it will execute a simple python AND perl script, which test all the dependencies required for launching the effects, and it report OK/problem form.

SO it would be easy for the users, if the effects is right installed or not. Im writing this idea, because there are many effects which require an external file, or an object to work on, or simply it does not seems to make anything (function plotter). So it would be nice to test, if the system right installed or not.

There is a crash related to this issue. There is a View->Scripts menuitem, what launched thereis a simple python script, what can be executed. If I launch it, inkscape crash immediatly. Here is the gdb output: View->Scripts, File->launch python program
