Comment 1 for bug 781244

Reproduced with Inkscape 0..48+devel r10207 on OS X 10.5.8 (i386)

Not reproduced with default 'px' units, but reproduced when changing the unit e.g. to 'pt'.
It appears that the units are not properly considered when writing/reading the value stored in the preferences.

A similar crash was reported in Bug #720699 in Inkscape: “Fill tool error. Inkscape crashes” - I'm not sure if the fix for bug #587769 only affects the allowed input values or caps the value read from the preferences, too.
