[SOLVED] Image caption: a bug in 3.4.2?

Hi all
here is a little problem I see in my 3.4.2 version. It's about the caption (or legend, explanatory heading, descriptive title.. i'm not sure of the traslation, sorry) you put under an image in a post.
Well, if you set in the options "Posts or excerpts on HOME page?" to Only excerpts and you set also in "Show the first X posts on HOME page as full posts?" a number as 2 (or 3 or 4...), it happens that when a post goes to position 3 in which it becomes from a full post to an excerpt, you don't see nomore the image, but his caption still appears as a single line between the byline and the body. Well, it's a problem.
This problem happens also when you have a page with all excerpts...
I had the 3.2 version it did not happen...

Is there a solution?
I do hope it's only a setting error i made...
Thanx in advance...
