Comment 3 for bug 55273

Similar problems here in Ubuntu Gutsy (=> Inkscape 0.45): When trying to render ANY valid latex string, inkscape hangs after pressing the OK button still showing the input dialog.
No error message in the console but in a file under /tmp (ink_ext_stderr_<somenumber>), I get this:
pstoedit: version 3.44 / DLL interface 108 (build Apr 29 2007 - release build - g++ 4.1.3 20070423 (prerelease) (Ubuntu 4.1.2-3ubuntu3)) : Copyright (C) 1993 - 2006 Wolfgang Glunz
PostScript/PDF Interpreter finished. Return status 2 executed command : /usr/bin/gs -q -dDELAYBIND -dWRITESYSTEMDICT -dNODISPLAY -dNOEPS /home/jules-k/psin3JohNg
The interpreter seems to have failed, cannot proceed !

Sorry, if I miss something obvious, it's in the middle of the night here ;)
