Hi François,

there always were some checks preventing malicious TeX input from destroying
vital data (search for '_name_ok' in kpathsea.info).  In Nov 2009 these
checks were applied to bibtex* in order to make bibtex a "safe" command. 
The problem is that bibtex writes the log (.blg) and bibliography (.bbl)
files into the directory of the (top-level) aux file.

BTW: there should be no problem when the aux file is in a subdirectory of
the current directory (specified as relative path without any '..'

Hi Karl,

how to handle this?
