Hi,

within one of the last commit 9fe26ec7307661efcc268a58293564fdb55e5572 you have modified the way popt strings are deallocated

while executing

Segmentation fault (core dumped)

the SIGSEGV occurs in the free(ipath) converter/babeltrace.c:677

for (i = 0; i < opt_input_paths->len; i++) {
char *ipath = g_ptr_array_index(opt_input_paths, i);
free(ipath);
}

This is probably due to the difference how the libpop is working. I'm using fedora16 with the following popt package:

Description : Popt is a C library for parsing command line parameters. Popt was
: heavily influenced by the getopt() and getopt_long() functions, but
: it improves on them by allowing more powerful argument expansion.
: Popt can parse arbitrary argv[] style arrays and automatically set
: variables based on command line arguments. Popt allows command line
: arguments to be aliased via configuration files and includes utility
: functions for parsing arbitrary strings into argv[] arrays using
: shell-like rules.
