WIN FR: Crash when launching program

When launching Inkspace, Dos terminal start writing:
"GLib: Cannot convert message: La conversion du jeu de
caractères « UTF-8 » vers
« iso_1 » n'est pas
support├®" in english:
"GLib: Cannot convert message: Charset conversion from
« UTF-8 » to
« iso_1 » is not supported"

then next lines are:
"
** (inkscape.exe:2480): CRITICAL **: Unable to load
stock pixmap RELOC share\icons\join_miter.xpm

** (inkscape.exe:2480): CRITICAL **: Unable to load
stock pixmap RELOC share\icons\join_round.xpm

[...]
** (inkscape.exe:2480): CRITICAL **: Unable to load
stock pixmap RELOC share\icons\properties_stroke.xpm

I/O warning : failed to load external entity "NULL"
"

and I have a warning dialog box (translated):
"D:\0users\Inkscape\preferences.xml is not a valid XML
file or you do not have rights to read it. Inkscape
will start with default preferences. New preferences
will no be saved." [Valid]

but the file exists, is a valid XML and I have all
rights on it...

When Validating it, Dos terminal continues:
"
I/O warning : failed to load external entity "NULL"

** (inkscape.exe:2480): CRITICAL **: file
extension/system.cpp: line 378
(Inkscape::Extension::Extension*
Inkscape::Extension::build_from_reprdoc(SPReprDoc*,
Inkscape::Extension::Implementation::Implementation*)):
assertion `doc != NULL' failed

Emergency save activated!
Emergency save completed. Inkscape will close now.
If you can reproduce this crash, please file a bug at
www.inkscape.org
with a detailed description of the steps leading to the
crash, so we can fix it."

An error dialog box appears:
"Inkscape encountered an internal error and will close
now." [Close]

When clicking [Close] a Windows error dialog box is
displayed:
"Instruction at 0x0000 is using memory address 0x0000.
Memory can not be read." [Ok] [Cancel]

then it close...

I had installed v0.39 with (directly) the Windows error
dialog box then never could continue, the Dos terminal
and other dialog boxes were new after having installed
Inkscape0411180200.zip.

OS = Win 2K pro SP4 French
