It's harder to debug on older version. But there will be related memory
leak, so maybe try using valgrind. You'll need to find the gst.supp from
the common/ repository, for this you need to find the Rev that was used by
your version (clone that tag, and look at the git submodule). That's best I
can give as my memory does not go as far as 1.8 (that's 4 major releases in
the past, so at least 4 years).
