How to find problem log

HI,

I am using XBMC Eden on Fedora 17, 32 bit machine (not certain as I was given the machine).

Today I tried one or two of the addons and find that for example, NASAtv is giving me 'Script fail: addon.py'.

The weather forecast (default is also not loading) but need to ask the following question first.

I would like to find the problem but unsure how to get the problem/bug report.

Thanks in advance.
