RSS subscription checker erroneously returns to 1-hour setting

[OmegaJunior]

Greetings,

Although I set several RSS subscriptions to check for new messages every 5  
minutes, after a couple of seconds the setting returns to "every hour".   
I've got some rss feeds I want to be checked as often as possible. Every 5  
minutes would be nice, but Opera doesn't seem to like that setting.

I set it (invoking "Properties" on the RSS feed in the sidebar), hit OK. I  
reopen the properties, it's still there. I cancel the dialogue, reopen it  
and poof, it's reset to an hour.
