muon-updater prompts to click missing "Check for updates" button

[skierpage]

When I open muon-updater, its Software Updates window is mostly blank and shows the message:

   It is unknown when the last check for updates was.
  Please click Check for Updates to check.

But there is no Check for Updates anywhere, not even in the [More...v] menu. I'll attach a screenshot.

This eventually is replaced by the available software to update and the [ Install Updates] button enables (or, it is replaced by "The software on this computer is up to date. Last checked XX hours ago"). But while it's on-screen it makes no sense.

I don't know whether the "It is unknown when" message itself is a bug, it appears even though muon-updater ran successfully last time.

This is on Kubuntu 13.10, Muon Update Manager 2.1.3 on KDE 4.11.5

Hi there!

Thanks for reporting this bug! Your bug seems to be a problem with the KDE program itself, and not with our KDE packages. While we appreciate your issue, it would be better if it was tracked at https://bugs.kde.org, so that the KDE developers can deal with this speedily and have direct communication with you as the reporter for more effective debugging.

Thanks!

OK, I reported it at https://bugs.kde.org/show_bug.cgi?id=331665 (doesn't Launchpad have some facility to track bugs in upstream?).

At other times the Check for Updates option did appear in the More menu after muon-updater downloaded latest information, and this didn't take very long.

The good news from the KDE bug report is the bug is probably fixed in muon-updater 2.2 series.
