After several tests I have pinpointed a problem with seems to revolve
around setting the PATH environment variable from within the dispatcher
script. Any subsequent exec command resulted in a crash.

This happens only with the binary dispatcher and *only* in the
udev-triggered context. Running the binary dispatcher manually from the
command line will succeed as expected.

Hi,

Thank you for your patch, I have not had time to test it.

With EnableLogging = 1 I had another crash which was recorded, I hope 
this helps.

The problem happens from time to time with the EnableLogging = 0. When 
EnableLogging = 1 I do not have this problem.
