[Tilesathome] inkscape stops rendering

[ben k]

hi,

I've tried to reactivate my t at h work ;)

set up a machine (AMD Phenom 9950 Quad, 4GB Ram) with ubuntu 10.10 desktop.
t at h is version 23290 (Vizag)
inkscape version is 0.48.0 r9654 (Oct 28 2010)

it stops nearly on every rendering with this:

12.01.2011 - 00:13:34[#1   0% tile-z16] Rendering...

I tried to investigate with  ps uawwx
and found the following process with SN+

/usr/bin/inkscape -z -w 4096 -h 4096
--export-area=0.000000:0.000000:878.906250:878.906250
--export-png=/tmp/12_2161_1323_uSx2F/tile-z16-s0.png
/tmp/12_2161_1323_uSx2F/tile-z16.svg

I tried to run this command manually in the terminal and inkscape
stops with this:

Background RRGGBBAA: ffffff00
Area 0:3,18187e-317:5,80243e-317:6,90248e-310 exported to 4096 x 4096
pixels (inf dpi)
Bitmap saved as: /tmp/12_2161_1323_uSx2F/tile-z16-s0.png

** (inkscape:14990): CRITICAL **: bool sp_export_png_file(SPDocument*,
const gchar*, const Geom::Rect&, long unsigned int, long unsigned int,
double, double, long unsigned int, unsigned int (*)(float, void*),
void*, bool, GSList*): assertion `!area.hasZeroArea()' failed

I checked the folder and there is no png despite inkscape says that.

any suggestions?

thanks,
ben
