bug#21457: 25.0.50; vc-test-git03-working-revision test fails

[Eli Zaretskii <eliz@gnu.org>]

This started lately, probably within the last couple of weeks.

The error information in the log is:

  Test vc-test-git03-working-revision backtrace:

What does the marked line mean?  What kind of error/problem should I
look for?
