Comment 1 for bug 1835671

I added some links to this problem, because the errors in these two questions (link bellow) are quite similar with what I just have described.
Don't know if the launchpad's link-to-bug function works well, so I just paste the links here.

This,

and this,

Have the same error just like what I have right now.
Hope all this helps.
