[TJ <ubuntu@xxxxxxxxxxx>]

I'm continuing to generate patches to fix-up path issues as I discover
them. At intervals I'm also re-publishing the updated package to my PPA.

I'm currently at revision 193 on my development branch.

I suspect I've got all the path issues now - at least there's no
remaining argv[0] references.

I hit an interesting out-of-memory error earlier that caused the
application to crash. The system was pushing the headroom, very close to
2GB allocated RAM and starting OpenShot seemed to be too much.

 Luckily I'm running it from gdb all the time so I was able to inspect
the reason via the call-stack which I'll reproduce here for future
error-catching work:

Program received signal SIGSEGV, Segmentation fault.
