We are testing things with Gstreamer and run into a similar error. It 
does the 'No such file or directory' thing but with 'Caught SIGSEGV 
accesing address (nil)' message.

We, newbies, dare to do:
   cd /usr/lib
   ln -s libgstfsl-0.10.so.0 libgstfsl-0.10.so
then reboot, and that message was over. Now we can run several times our 
command.

Here is an iMX6Q Sabre Lite board, and it happens with yesterday 
master+linux-imx and dora+linux-imx branches.

We have to change from linux-boundary to linux-imx because we moved to 
an HDMI monitor. After that, linux-boundary hdmi driver keeps giving 
messages and hanging the system.

Thank you
