So what is your question?

How about, "what was your intention?"

KiCad data files should be using the "C" LC_NUMERIC setting. Anything you see other than
that, is indicative of something having gone wrong.

It seems to me that his intention was to report that these SVGs had
*not* the C locale, since were output with the comma instead of the
point... so probably there is something wrong.

There are suspicions of a recent bug, which would cause the call in

    LOCALE_IO::LOCALE_IO{}

which sets the "C" locale, not to fire if you had previously done a "Load All" in the
footprint picker. If the variable C_count got out of sync with reality, then this could
happen.

Last night a probable fix was committed. So maybe the problem is now gone. Time and
testing will tell.

Updating to 2014-01-21 BZR 4628 seems to have fixed the problem for me. Thanks for the quick response and sorry I didn't update before posting; it didn't seem possible at the time because the repository path apparently had changed and I hadn't noticed that until a moment ago.
