Launching the SimSig launcher with Wine 6.11 and libxml2 2.9.10 works fine.
After upgrading to libxml2 2.9.12, the software no longer works properly, and
the following shows up in the console output:

There is a lot more output, but it is either benign messages that also appear
with 2.9.10, or else repeats of the same messages.

I have recompiled Wine after installing the new libxml2, but that did not make
any difference; the problem still occurs.
