The PathHandler has code to handle absolute pathes. It tries to analyze
the path to see if it's a Windows or Unix path, and if it's a Windows
path checks the second character for ':' to see if it's absolute. The
only thing I could imagine is that the Win32 detection goes wrong on
your example (well, either that or there's a bug somewhere :). What was
the exact path you tried it on? Can you try setting the OSG_LOG_LEVEL to
notice? In that case the PathHandler will print info about which pathes
it tries.

We thought about adding that as a default, but then you would have to
have specific API calls to remove it in cases where you don't want it,
thus we decided to have the users add it explicitly. It just some thing
you need to know, as it's not a big deal to do it.

Integrated, thanks for the patch. Is there a specific reason for using
the FLOG? FWARNING is generally more appropriate.
