Guys,
I'm having this problem very often, I don't know why a wifi setup file
is been created empty and the next time I boot my device (run connman)
connman crashes.
I tested with 1.8 and 1.9, still crashing.
Here is some output from valgrind:

My investigation lead to this:
inside static GKeyFile *storage_load(const char *pathname), is tested
if the file is empty and returns a NULL. So probably somewhere someone
is been trying to access a NULL pointer or something like that.
Valgrind shows that g_key_file_get_value() is the one causing,
apparently, a SEGFAULT.
The only place in connman's source that g_key_file_get_value() is
called is: src/storage.c:485: value =
g_key_file_get_value(keyfile_def, services[i],
But the problem is that I don't know if that call is from connman or
from inside glib.
Please, does someone with more experience with connman could help me
finding this bug.
By the way, I'm using ARMv7 architecture.
OBS: It doesn't matter if I run with '-I eth0' or not
Thank you,
Felipe Tonello
