Hmm... this might be bogus, as my upgrade to Kubuntu 14.04 is quite 
recent.  It may be that the culprit is NVidia XOrg driver or some such 
issue, as it seems other apps besides Qt Creator are also acting funny.

Almost as if the USB stack would go garbage collecting, affecting both 
keyboard and mouse with occasional pauses...

So for the time being I'd chalk it up to system specific anomaly. I have 
an another machine on which I need to cross check.

So unless other reports come in, I'd leave off the investigations for 
now until I have something more concrete.
