Looking at this now, it stirs vague memories from when Ritesh and I were 
building things in early summer and, I think, we had complications with 
using qcc versus gcc... does that ring a bell Ritesh?  I think we had to 
force certain things in the command line arguments which, if true, might 
be visible in our build instructions.  I'm personally too long out of 
the C++ world to really be much help on such things.

I can eliminate this as a possibility. I've loaded .so files from system 
folders, the app's own app/native folder, the app's data/ folder, and 
even shared/misc without issue, whether the folder is in the 
LD_LIBRARY_PATH or not (i.e. giving full path works too).

Almost certainly not the case either, since we've never been able to 
blame anything on the prebuilt interpreter yet. They've actually made 
the source available in a private repo, and some of us have reviewed it 
a bit. It's pretty vanilla, with a few QNX-isms but nothing that I'd 
expect is relevant here. Anything's possible of course, but this one 
seems very unlikely.

Micke, Ritesh, does his segfault ring a bell?  Somehow I think this 
one's actually got a simple fix but I've erased too many PySide-related 
things from my brain in the last few months.
