On OS X 10.7.5:
- not reproduced with Inkscape 0.91+devel rev <= 13836
- reproduced with Inkscape 0.91+devel rev >= 13841
(no archived builds in-between).

Possibly related to implementation of new textLength and textAdjust attributes (?):

With rev 13824-13836 (no crash), there are already these messages on the console:
SPObject::~SPObject(): someone else still holding ref to style
SPObject::~SPObject(): someone else still holding ref to style

Full backtrace with debug build (r14057) attached.
