Do not keep trying to mount when it fails
Refs #10221
If a USB stick (or other removable drive) is attached to the frontend, and the user running the frontend is not able to mount it with "mount /dev/sdc1" or the like, we do not want to keep trying (twice a second!) to mount it. There's no purpose to that other than extra load, and filling log files with useless crap.

I can not reproduce the crash. However, the repeated mounting is now gone. If you could retest and see if this does it for you, I'd appreciate it.
Also, just a note: for the QDbus stuff to work, (in ubuntu at least), you need the "dbus" and "udisks" packages both installed.

Without the repeated attempts to mount the segfault is no longer repeatable.
I think that this looks more like a problem with memory corruption. Certainly the backtrace shows the exception is in MythMediaDevice::performMountCmd (called from the patched MediaMonitor::CheckDevices?) but the failing line is a LOG output and Qt is simply formatting a string.
Earlier in the log are numerous lines showing the attempted mount command without problem. Would be useful to see a valgrind run.
