A "final" update, just to close my own thread.

Case 1: It happens during "cmake ../" for gnuradio. It's caused because python 
imports "hashlib", which in turn imports "_hashlib". Manually enter python and 
"import _hashlib" triggers the kernel log above.
 
Case 2: The situation above ("from gnuradio import gr_unittest") boils down to 
an import of _ssl. Same thing, a manual import of _ssl in python triggers the 
same.
 
Using sys.modules.values() in python to see the libraries loaded for each case, 
and then ldd to see the dependent libraries, there are 7 in common between 
_hashlib and _ssl. The one I most suspect is libcrypto.so 
(/lib/arm-linux-gnueabihf/libcrypto.so.1.0.0), which is the only one of the 7 
that didn't come from the Ubuntu Core I am using 
(ubuntu-core-13.04-core-armhf). I believe it was installed as a dependency of 
installing git (which installed libssl.so.1.0.0).
 
My conclusion: maybe this is something to report to Ubuntu Core maintainers.
