MintUpdate not working under KDE (SOLVED sort of)

[JoeInMN]

Installed Mint17 Cinnamon on my new laptop with no real problems, but decided I still prefer KDE, so installed kde-full on top of it, also installing KDM and making it my default DM. I now have an odd issue with the Update Manager. When the panel icon shows that updates are available, I click it and the window comes up normally. However, when I click "Install Updates," rather than asking for my password, the window simply closes. MintUpdate doesn't quit; the icon stays active and I can repeat the process ad infinitum, but it won't ever actually run the update routine. I can log out and come back in under Cinnamon, and it will run normally there, so apparently it's having some problem specifically with KDE/Plasma. I can do the dist-upgrade via the terminal, but I don't always want to apply the entire kernel update packages too.

Here is the entire sysinfo report for my machine, in case any of it is relevant:

This seems to be the only significant issue I have left. Thanks for any help anyone can offer.

...aaaaand now the issue seems to have resolved itself. Don't know the what, the how, or the why of it, but MintUpdate worked normally just now. So I guess I'll mark this SOLVED, even though that doesn't really feel like the right word.
