Until ​bug 736260 in pygobject/pbutils has been fixed, we get these warnings whenever mediagoblin is run:

…/lib64/python2.7/site-packages/gi/module.py:178: Warning: g_array_append_vals: assertion 'array' failed
  g_type = info.get_g_type()
…/lib64/python2.7/site-packages/gi/module.py:178: Warning: g_hash_table_lookup: assertion 'hash_table != NULL' failed
  g_type = info.get_g_type()
…/lib64/python2.7/site-packages/gi/module.py:178: Warning: g_hash_table_insert_internal: assertion 'hash_table != NULL' failed
  g_type = info.get_g_type()

Attached is a patch to workaround it - run Gst.init() before the import.

The return type of tags.get_string is a tuple, (bool, value) (ref ​https://lazka.github.io/pgi-docs/Gst-1.0/structs/TagList.html#Gst.TagList.get_string) This code assumes that the return value is just a string. As such, it will always return False.

Example:

39 if configmime_types and tags.get_string('mimetype'): 40 if not tags.get_string('mimetype') in configmime_types: 41 return False

If there is no mimetype string in tags, then tags.get_string('mimetype') returns:

(False, None)

Which allows the test on line 40 to pass. Of course, (False, None) does not appear in the list of mimetypes in the config.

In each case, the initial existence test needs a [0] after the get_string, and the second test needs a [1] after the get_string. E.g.:

39 if configmime_types and tags.get_string('mimetype')[0]: 40 if not tags.get_string('mimetype')[1] in configmime_types: 41 return False

devtools/update_extlib.sh uses which to look for bower in $PATH. However, it doesn't redirect stderr to /dev/null, so the user sees a misleading message if bower does not exist in $PATH. This causes the user to think that bower is being reinstalled every time devtools/update_extlib.sh runs.
