[gaim-migrate @ 17356]
After the comments on gaim-devel about 'bad' code, I looked into the function referenced. It appears that yahoo_buddy_icon_upload_connected() is only called as a callback. It's registered from yahoo_buddy_icon_upload(). yahoo_buddy_icon_upload() is only called twice. In neither case can a NULL make it down to yahoo_buddy_icon_upload_connected(). As this is an exceptional case rather than a normal one, a g_return_if_fail() is more appropriate. That adds logging, makes the intent clearer, and will help the Coverity software detect violations of this assumption.
