suggestions for "Could not load extension"-dialogue

Hi,

As part of the bug submitted against the debian package
of ver. 0.41 at
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=294930
I got some suggestions from Andreas Neudecker, I want
to submit here. He reports about the "Could not load
extension"-dialogue:

Additionally, the error dialogue should produce some
more helpful information.
"Go, look in ~/.inkscape/extension-errors.log" may not
be helpful for many users.
If the program can write that information to this file,
why can it not produce
the same information in the error dialogue? It might
even be put in
understandable terms, like for example:

"
Could not start extension "Windows Metafile Input".
Reason: Program/library package "libwmf-bin" is needed
but was not found.

Could not start extension "Postscript Input".
Reason: Program/libary package "pstoedit" is needed but
was not found.
