Installed missing debug symbols, the top of the trace is really:

Program received signal SIGSEGV, Segmentation fault.
0xb7dbf772 in free () from /lib/libc.so.6
(gdb) backtrace
#0  0xb7dbf772 in free () from /lib/libc.so.6

While #6 is #19 from the earlier trace:

This is 100% reproducible for me on a clean install (rm -rf
/var/lib/smart/channels/* etc.)

[patrys at meaw SPECS]$ rpm -q python-pycurl
python-pycurl-7.16.4-1.i686
