Dear errors.ubuntu.com,

This version does not exist in the distro, but it seems the bug does anyhow. I believe the problem is in this line:

            dp->profiles = pa_hashmap_new_full(pa_idxset_string_hash_func, pa_idxset_string_compare_func, NULL, (pa_free_cb_t) pa_droid_profile_free);

This line, located at src/modules/droid/droid-util.c, should be removed. It is already created at pa_device_port_new. And there it is also correctly created without a call to "pa_droid_profile_free"; this is what leads to the double-free reported above.

[David Henningsson (diwic)]

However, maybe this line was added for a reason so it would be good with some testing before release. Could anyone help out with this?

This package version is available from the overlay PPA.

Perhaps you should follow up with the uploader of that package.
