error filename for export

Ubuntu Hardy Beta (up to date)

In the export window of inkscape,when i take right-clic open with Inkscape, if i will export

the default directory for the export is /home/jimmac/Desktop/thefile.png (or other)

but i'm DJ not jimmac :s

with somes files there are this problem, with other no

example

for /usr/share/icons/Tango/scalable/apps/compose.svg the home directory is /home/lapo/Desktop/xubuntu/pngs/compose.png
for /usr/share/icons/Tango/scalable/apps/ the home directory is /home/jimmac/Desktop/wi-fi.png
but for /usr/share/icons/Tango/scalable/apps/accessories-calculator.png is good (the default folder for export it's OK, it's /usr/share/icons/Tango/scalable/apps/accessories-calculator.png )

I thinks that there are somes other files but i don't have the time for see all svg

but if we open the svg file with a text-editor we see (for examples)

inkscape:export-filename="/home/jimmac/Desktop/wi-fi.png" or inkscape:export-filename="/home/andreas/projekt/tango/scalable/kontact.png"

can you delete all inkscapre:export-filename ?
