Profiles randomly stop working.

I've noticed recently that every here and there I won't be able to view another persons summoners profile, this only happens when I try to view someone on my friends lists, or someone who I recently played with. This then prompts my own summoners profile to not allow me to view it. I could click the my summoners profile a million times and it simply would not open. The only way I've determined I can fix this issue is if I restart my client.

Anyone else having this problem as of late?
