yet another crash with non-ascii filenames

[Buliabyak-users]

Sorry Jon, I know this is becoming annoying :)

Attached is the zip file with an SVG with non-ascii
filename (in my filename encoding, which is KOI8-R).
Opening it from GUI or from command line works fine.
However when I try to export it from command line it
crashes, obviously attempting to open some error box
(again!). The space in the filename does not seem to be
the reason, i.e. it also crashes for another KOI8-R
filename without spaces.

$ i не\ знаю.svg --export-png=test.png

I would not call it fixed, latest CVS does not crash but
does not work either:

Yes, fixed.
Crash and screen failure were from certain causes and with
certain symptoms. Those have been fixed.

Not opening is a different cause, with different
user-visible behavior, so if it's still there after this
latest code update, open a bug specifically on that.
