OK, committing to the trunk and to the 4.3 after test there...

I checked that PR and the valgrind output is clean now, and the
valgrind backtrace in comment #1 definitely points to the same issue.
I did not test without the patch to see those errors though. I will
add note to that PR after commit. I cannot decide that this PR could
be closed as well, as probably real file names in diagnostics should
be reported instead of /tmp/... . This would require exactly the
change the FIXME in the patch suggests.

Thanks,
