tried it with the latest snapshot (Version 4.3.5RC2-dev) on a Windows system and the problem seems to be fixed.

Will try it on an unix system also and report my findings.

BTW, if you want to reproduce this bug, just cut and paste the following source, which will produce a mail as mentioned, into a file:
