No clue how to report it to google gadgets lib??? Any pointers???

Anyway, if it's causing Plasma to crash, I'd think it would be a bug in plasma as well. No matter how mis-behaved google gadgets lib is, it shouldn't cause plasma to crash....

[Comment from a bug triager]
It is already reported to Google Gadgets (described at bug 251923)

About Plasma crashing due to plugins: look at bug 199754.
