#1194: PlaybackBox::updateUsage() will crash with floating point exeception

 Priority:  minor           |   Milestone:     
Component:  mythtv          |     Version:     
 Severity:  medium          |  
----------------------------+-----------------------------------------------
 PlaybackBox::updateUsage() in programs/mythfrontend/playbackbox.cpp will
 crash with a floatingpoint exception during two conditions:
 1. The total amount of space left is less than 1024 bytes
 2. The call to RemoteGetFreeSpace() doesn't return any info (More likely
 than the previous in case of backend down for example)

 The problem is line 940:
         double perc = (double)((double)freeSpaceUsed /
 (double)freeSpaceTotal);
 where freeSpaceTotal should be checked for 0 before usage.

 I Would attach a patch, but as it will involve artistic decisions about
 what to report as usage and freeI think I leave that to the core team.
