I wanted to post this as a bug, but I don't even have a clue to whom should I report it. Here it is.
I have installed Odoo 9.0 on a standard Alpine 3.5, with both the packaged Python 2.7.13 and I have also tried with the same version of python compiled from the sources, but the result is identical:
When I navigate from any view in the Odoo application to the Accounting dashboard python segfaults. The odd thing is that if I copy the URL of the Accounting dashboard and paste into the navigation bar – this way forcing a load of the entire page – it all works ok. I tried gdb on the python interpreter to see what happens. The error seems to be mostly consistent, but unfortunately the information I got is not that helpful:
Thread 34 "python2" received signal SIGSEGV, Segmentation fault.
[Switching to LWP 13754]
0x00007ffff7dc52f5 in sem_timedwait () from /lib/ld-musl-x86_64.so.1

#1 0x0000000000000000 in ?? ()
On very rare occasions the error is different, I managed to catch it once in the debugger:

The stack trace in this case is quite long, this is just a fragment. Just to get that out of the way I did try with both the grsec kernel and a vanilla one, same result.
I'm rather new with python so any ideas on how to debug further, or workaround this issue would be greatly appreciated.
