Cannot remove one RSS feed subscription

[drunken monkey]

Binary package hint: thunderbird

For all other feed subscriptions, this seems to work normal, but removing the subscription for [1] doesn't work. When I try to remove it, nothing happens after I click "Yes" in the confirmation dialog. No error message, no console output – the feed just stays were it is.
Version is Thunderbird 3.1.8, under Ubuntu Lucid.

I can not remove any of my feeds. They where imported from opml initially.

I checked, and the feed is not in my subscriptions anymore (I'm also on Arch now), so apparently I succeeded in removing it at some point.
Closing with “Fix Released” seemed the most appropriate, hopefully that's correct.
