Attached patch fixes this.

Disregard the "tabbed-links" change in the patch. grunt rtlcss caught that.

Looks fine!

@hnla - Can you sign off on this? Just want to make sure you're aware of the problem and if the solution is good enough.

@r-a-y It looked good, running patch to check in more detail.

@r-a-y The proposed fix is good, isolated to the act stream avatar should be safe. It did make me wonder though why I didn't add a global rule & thought I had e.g #buddypress .avatar {height: auto; max-width: 100%} which would trap any issues like this. Better is we don't specify the image width/height atts which causes the issue when height auto isn't explicitly set to override.

Lets commit this patch, it corrects issue for smallest cost, thanks for spotting.
