[kdenlive] Can't seek within any video

[Brian Cluff]

I just upgraded my main computer to Kubuntu 15.10 after having some very 
good success with it on a couple of my laptops.  I completely skipped 
kubuntu 15.04 and just ran 2 upgrades back to back without rebooting. 
After upgrading kdenlive would not allow any seeking in a video no 
matter if it was playing out of the project bin or in the time line, 
making the program completely unusable.  I initially figured that it was 
because I was running a beta version of Kubuntu and that kdenlive may 
have been packaged with it's dependencies messed up, but other people 
seemed to be have little to no problems with it.

I then tried the same thing on one of my laptops and it seemed to work 
fine, which then prompted me to delete anything that looked like a 
kdenlive config file from within .config and .kde.   Once those were 
gone everything seems to be working again.

Anyway, I guess I'm just posting this just in case someone else runs 
into the same problem they might be able to fix it quickly and perhaps 
if the particular offending configuration parameter can be located that 
isn't compatible with the new kde5 version it could be automatically set 
to something that doesn't render the program useless.

As always, thanks for such a great editing program!
