Having the same problem here.

At first, I thought the text dissapeared after I installed ogg-support-lightmediascanner... but after few tests it proved (or at least seemed to) have no effect on this.

Uninstalled everything with connection to Canola, even cleaned up settings... all to no avail.

Anyway, at least we can see the updates in status bar now. Hopefully one of them will fix it :-) .
