When I run the createrepo command (from the createrepo_c package) in Leap 15.5,
such as:

/usr/bin/createrepo --update
/home/mrbill/Documents/repositories/codeweavers/openSUSE

I get the error message:

C_CREATEREPOLIB: Critical: cr_metadata_load_xml: Error encountered while
parsing

and createrepo seems to go into an infinite loop and must be killed.

Here is the package information and full command output:

createrepo_c-0.16.0-3.3.1.x86_64
libcreaterepo_c0-0.16.0-3.3.1.x86_64

I have been running this command for many, many years, beginning on a now very
old, pre-Leap version of openSUSE, and do not remember ever having this
problem.  I also boot Tumbleweed on the same PC, and it works as expected. 
Here is the Tumbleweed package info and command output:

createrepo_c-1.0.2-2.1.x86_64
libcreaterepo_c1-1.0.2-2.1.x86_64

I thought someone should know of this problem.  Thanks!
